KDStudios I have a question. I’m not able to run the H2test because I’m on Mac and don’t have the necessary items to use it on that. So I bought a 128 gb Samsung micro SD and I found it wasn’t storing more than 36 GB oh my switch. It’s very odd because it came in sealed packaging and looks very real but I noticed the edges are black and from what I read that’s asian it’s a fake. When I look at the storage capacity on switch it has a black bar that prefills up all except about 90 gb of it. When I went to download a game to it it would only take two games before it said it was filled, even though those games only rallied up to 30gb. Is that a good enough sign that it’s indeed fake and formatted to appear 128?
THANK GOD! Mines is real! It said "test finished without error", I purchased mines off some tacky eBay shop that even I had my doubts about. Thanks dude! :-)

Keep in mind that operating systems report sizes in multiples of 1024 (binary: 100-0000-0000, hex:400, easy to remember and do in your head) and drive manufacturers report in multiples of 1000 (binary: 11-1110-1000, hex:3E8). Anyone that says computers should report as 1K=1000 has never programmed in Assembly, or is just an asshat, or both.
my factory manufacture the USB flash drive in shenzhen for 10 years, which 100% pass the H2TESTW . Before we do the assembling , we need test each usb flash drive in H2TESTW . H2TESTW is really helpful . But there are still a lot buyers want the super cheap price usb flash drive ,like 1 dollar or 2 dollar ,really crazy . Those low price chipset ,we call it upgrade type chipset , the real capacity is about 128mb . But it display on your PC is 16GB . The only way to find it is using this H2testw to test .
Can you help me? I have a newly-bought 32Gb SD Card Class 10, I tested it using H2testw and showed no Errors (No Bad Sectors nor anything). But when I put it in my phone, I always lose lots of random files on the SD right after rebooting my phone. Especially, when the SD Card Used Space has reached more than 16GB. The lost files tend to change themselves to 0,00B in Size and sometimes they move themselves to SDCard/LOST.DIR Folder.
Hello, Everyone. I need a help, I've been using my (Rooted) device for the last 2,5 years and lately I keep losing Data on my New 32 SD Cards (Such as Images, Mp3, and other files). For this month only I already purchased two genuine 32SD Cards. I bought the first one 3 weeks ago, then I transferred all my files from my old 16Gb Card Onto the Newly-bought one. And whenever I restarted my phone, I always lost 2-8Gb of files. For instance, before I restart my phone there was 8Gb of Free Space & 20Gb of Used Space on the SD card; but after restarting my phone the free space mysteriously went back to around 14-15Gb and the used space also went back to 14Gb, meaning that I just lost 6Gb of Random Files (The disappear files' sizes tend to change themselves to 0,00byte or 32,0Kb). I've Tried Formating The Card & Re-transferring again for like 10 times, but the problem still persisted. And i'm tired of this, because it needs more than six hours to transfer all my data worth 20Gb (from my Flashdrive & Card) to the abominable Card; but in the end 6gb of it will eventually lost. The card simply, can't hold more than 14Gb of Data on it (if I put files more than 14Gb of files on it, some random files will eventually disappear & corrupt after reboot and the free space goes back to around 14-15Gb Again) but it only happens on this phone (Because the card is 100% pure 32Gb Class 10, and I had tested it using various softwares on PC and they all tell that the card is genuine). At first, I thought the (First) SD Card was fake/fraud product so then 2 weeks later for the second time, I bought another 32Gb Sd Card with a different brand (which now I'm using). I also tested the Card on PC Using H2testw prior to using it, and test results showed that The 2nd card is also 100% Genuine (No Errors & Bad Sectors). But today is my unlucky day, because I Rebooted my phone that had been On for the last 11 days. I knew this would happen again because the first 32Gb Card also has similar problem despite the card being genuine (Everything is fine if I don't restart/reboot my phone). I kept my phone awake for more than 260 hours, because I knew If I ever shutdown/reboot my phone I would lose lots of files. BUT IN THE END I will always need to reboot my phone knce in a while, and I just lost random files again (today's loss was 1,8Gb). The questions are, Are the SD Cards actually Counterfeit Products? Does this problem have something to do with my firmware (ROM)? Does My phone have bad Motherboard? Does this have something to do with the TWRP (Custom Recovery System)? What should I do To fix this problem? Kindly, I'm seeking for help.
that means your SD card real capacity is about 16GB ,not 32GB . Can you show a screen shot of your H2TESTW result . Your SD card seems to be the upgrade SD card .
Why didnt you just test 32 or 64 if you are suspicious? Regardless 4 hours of waiting is better than a week/month of issues down the line when you notice youre losing data.
@@ThePizzaByte I have a 2tb usb stick that I just realised it is saw as a hard drive due to it only having exFat and NTFS, but when I transfert video and picture, I often recive the error 0x80070570, do you think there is a permanent fix to that or will I simply have to worry all the time about corrupted files ._.
It's getting ridiculous how many counterfeits there are out there. I bought a 64GB drive for $8 and a 16GB driv for $5 from the same supplier as I needed 72GB to back up my music with the HE-AAC v2 codec (just because I can) and the 64GB turned out to be a 16GB counterfeit. So I ended up with two 16GB drives. But what's the bloody point of doing that? I got my money back but the really annoying thing is the seller wasted everyone's time, both mine and his with his stupid little scam. As if people are really not going to notice there are 48GB missing.
My 1 tb micro sd has been going on average of 7.08 Mbytes/s and is at 88hrs 47mins and says 10.2 Gbyte OK 716.5 Gbyte DATA LOST/corrupted. I was wondering why after around 8gb, every file before that mark would be written over with whatever new files were added. This video helped out a lot, thank you.
Oof, I should have said the moment you see Data Lost/Corrupted you may as well take a screenshot and end the test as the rest usually will result in a failure also. Instead of waiting for it to finish. Really wish fakes would disappear. If you are to keep the SD card be sure to delete the partition of the SD card and make a new one with a limit of 10GB, that way you can use it until it's real capacity.
@@ThePizzaByte the seller immediately accused me of breaking it by unmounting it improperly when I had files being written over. I knkw this issue is in no way related to removing an sd card prematurely. I am doing this and taking screenshots every 5 hrs to include in my email to remove any excuses he may try to give me to shift the blame. If he were an honest seller, I would definitely have done whag you recommended. I appreciate the rather quick response you gave!
What these vloggers do not tell us is on how many hours does usb tester does the process. As of writing i tested my 2tb USB for almost 5 hours using h2testw but the bar does not even reach 1/8 of its status. This is a very tiring process but i have to wait for more hours I think provided I won't get bored of waiting...lol
omg bought a 126gb sd card but only tested at 64gb (65536mb) and the verifying corrupts after 31.3gb..... does that mean that sd card is only at 31.3gb? i have trust issues
I'm in the process of testing my Aliexpress 128gb USB memory stick. I've already had problems with it. If you make a folder , the contents of the folder dissappear. Oh dear, I will tell you in 7 hours if the results are bad. But its only writing at 3.72 MB /sec
I should have said in the video, when it comes to large sizes like that, chances are they're much smaller. For that one I'd strictly test 32-35GB and no more. If that comes back as successful then try the whole 128GB, but chances are a lot of them come back as 4GB/8GB/16GB/32GB Memory sticks never usually more.
probably the greatest thing about getting fake drives is that the seller rarely wants it back, you'll get your refund, and you get yourself a free XXGB drive. I bought a "2TB" card, hoping that there is actually close to 256GB, but we'll see. UPDATE: The flash drive ended up only being 32gb. Lol yikes
I recently ordered 4 400gb micro sd cards on ebay for about $20. So far 2 have been tested and came back as 32gb micro sd cards. I got my money back without returning the sd cards but bummed they wasted my time.
I encountered same problem. Can we stop sales website from becoming a place where fake products are sold? They should investigate and remove fake products to protect customers. If they do not do this, then they are accessories to the crime of cheating customers. Any idea?
I’ve learned from my past mistake of trusting cheap flash drives online and so I lost a couple of files, but fortunately I recovered the data from the previous location so it's all good. This time my mother bought an unbranded flashdrive online but didn't want it and so she gave it to me and I was shocked to see that it had about 900+ gb inside. Of course I don't believe that it truly has 900+gb inside and so here I am watching this video.
testing the 256GB microsd card i just bought. 7GB and still running lol 8 hours to go Edit: i just realized that it's 8 hours for writing and another 8 hours for verifying lol good luck to me
I recently bought two 256gb EVO Plus from a new/small seller on eBay & tested one which took almost 38hrs to complete both Write+Verify combined using my old computer with USB2.0 Turned out, only 30gb was usable which meant it was a 32gb card. It truly sucks that only a handful of us tested these cards & left negative feedbacks while the rest of the 100+ buyers were oblivious to the merchandise they received & just assumed they were real, leaving glowing positive comments, LoL. This experience was a good lesson in learning how to differentiate the fakes from the real ones... yeah, I had to buy them again except this time it was with a big seller who I bought a new Galaxy phone from just a few weeks earlier. And, it was more than just 2 as they were offered as a whole case Lot of 10 pieces... needless to say, it was a great deal & I now have enough to not have to ever worry about dealing with scam sellers any more =D
It's the drive itself telling your pc to read "128 gb" instead of it's correct capacity The drive is the problem so just use a program to fill it with data and data overwrite
@@casmsfrought9956 but isn't it once you start "over filling" it's capacity that it goes haywire? I've had USB's bought from Big Chain stores years ago that I never checked and within 3 months all the folders turned into random strings of nonsense. The store wouldn't take them back even though they were the only one's who stocked that "brand" @KDStudios
Glad it helped, get that sent straight back. Although me and the missus had a right chuckle at the capacity being bigger when it's meant to be smaller. Funny find lol.
Great video, Thanks for that, I bought a 2TB USB stick on Ebay for around £5 and lost much of the 60GB that I transfer onto it even though I comes up as a 2TB stick! How do I change it from 2TB to actual? Just rename it? Thanks in advance!!
I've still not found a way to "hack" them back to their original sizes, but I just rename them to remind myself their actual size. Then they work fine so long as I don't exceed the real size.
My 64gb sd card says the media is most likely defective but it has 58.4GB OK so does it mean i can still use the 58GB? without getting my files corrupted?
The Data volume section ies greyed out and wont let me choose all or any other amount??? I chose the drive properly first. It will only test 138 MB ?!! less than 1 gb out of 500 GB. SO now I just gona copy files to it to verify. It was not super cheap, price seemed right I just wanted to test before deployting.
The union soft external hard drive from the amazon is legit, i checked and i bought it and it said 250 gb but it gave me 230 but it takes some because the system requires it i think so it seems legit and the download speed is around 20mbps so pretty good for a small portable external hard drive
Infernox 2014 oof this comment is old. Yea I got a 32gb and my switch games kept getting corrupted. I ended up breaking it in half Bc it’s a useless piece of s***
It instantly returns an error saying it’s “write protected”. Is this something I need to fix before running the test or does it mean it’s bad? Edit: I had the switch on the physical card was set to lock. Don’t do that.
The SD card I bought is write protected and can't test it using H2testw :( . I have tried removing the write protection but all ways to no avail... how can I test this SD card I have?
Most scam drives have fairly small real capacities. I wouldn't test beyond 65 gigabytes. If Verify comes back at that point and stays it's still good, then it's likely that the rest of the drive is ok. Also a modern USB flash drive with a huge capacity should be writing at USB 3.0 speeds at least. Check the write speed while it's testing. A scam drive is more likely to be a slower, USB 2.0 drive.
Recently bought one that claims to be 2 TB (Has there been an actual TB USB drive before?) testing it now to verify what it claims to be but I doubt it is.
Yes they do exist. However, just test only 70GB (70000MB in the program) first. If it loses ANY data, it's fake. Or if that comes back fine test 130GB, then 270GB etc. Just to be sure. Testing 2TB will take forever.
Open Disk Management (Search for partition into the start menu) then delete the partition of the SD Card and create a new one with the actual storage capacity it has. HS2testw will let you know how big it is when finished testing.
I just buy a 1tb microsd card for fun (RM23 only)plan to make a video aswell but when running test. after 2days. it show 62 hour left. and I dont see error yet. now tested 260gb... l going to left it run for another 62 hour... btw the writing sppeed at 3.37mb/s == dame slow
I also bought 512gb OTG for my iPhone at Shopee for like rm38. Also testing it using H2testw, now it’s writing at 210gb & 5 hrs left. Assuming verifying will take another 12hrs I can do some laundry 😂 but the speed is faster, aroung 15.8mbps
I ran this and fakeflashtest on an SD card I got from eBay that was supposed to be 128GB (already got a refund because it arrived two weeks late, the seller emailed me directly and their account was deleted from eBay). They both say I've got only 117MB of space, and that the rest is corrupted. However, I put a 900MB video file on it and it ran all the way through without errors. I'm so confused :(
I've bought a 32GB sd card, which appeared to be fake, It has 114 mb storage only! and yes i can fill it up with a movie of 1GB but after a while i get an error message while playig it. Also pictures are not shown up in the gallery app saying "cannot generate thumbnail". I thought something was wrong with me phone but I bought a fake ass sd card
The reason this happens is that the SD card will just rewrite itself continuously when it runs out of space on these fakes. So to your PC it's copying fully, but if you tried to play it back it would either be completely broken, or highly corrupted. When these programs write the data, they generate a hash signature that's verified when the data is read back. Essentially making perfectly certain the data contained (fully filled) on the SD card isn't corrupt. Another helpful tip is noting the write/read speeds when the test operates. Especially for higher end cards that have ~90+MB/s read/writes. If it's only giving you 2MB/s on linear reads/writes it's probably fake.
I bought a 2TB external drive for £30 from eBay to store recovered data from a genuine 1.5TB Fujitsu drive. I just copied across about 500Gb. Shit, Shit, Shit. It only took 30 hours to recover.
welp, rip the 256gb card dudd i bought. i ran the test on it, it took over 16 hours [mostly to verify] and unforunately, a power outage restarted my PC in the middle of it. but from my recent screenshot of the progress- it was 68kb OK and 147.5gb _[and counting]_ DEFECTIVE... that's more than ha l f... way more than enough evidence to prove it fake. i think it was a 16gb card because i was able to fit around 12gb of stuff on it before it started bugging out ;/ bummer
I bought a Blue Wave 256gb sd card off Wish. Its given me nothing but problems. It freezes up my phone, it deletes my music and corrupts my vdos so they are unplayable! I dont believe it is 256, its prob not even 128, maybe its 32? You get what you pay for.
How can you test to ensure the memory card is the actual brand you purchased ? Maybe you buy a 16gb card, it is 16gb, but it might be branded as something it is not ??
Honestly, unless you're selling the items it really doesn't matter. All that matters is that you're getting the speeds and the capacity you pay for. I hope this helps. Thankfully this tells you the read/write speeds and the capacity. Google the speeds your card is supposed to be at and also check to make sure you're using USB 3.0 so you know you're getting the best possible speed.
u can do the same test with aida64 btw, i bought a 2tb, well not me i know its a scam, but my sister insisted she knows someone who bought a 1tb usb stick and everythings great, i said to her probably its great with a few files that work, rest is lost, she insisted on buying it for me for 4€ so i said what the hell, itll be fake anyway. Did get it, tried it, it showed 1.9tb free, i said sure, copied a few files and was ok. Tested in aida64, first test showed a quick 753gb somethign, i was like, hm could it be the capacity is well not 2tb but at least 750gb is still good enough for this cheap. Well no, turned out, when i performed the write test and verify, well it showed only 15gb could be realistically wrote on this drive, but i think well its still ok for 4€ but not near 2tb, then i went online searched for 2tb flash disks, well the cheapest is like for 200€ and its a disk not a stick (i dont think they are the same) i think brand is Patriot and the most expensive on that list was for 330€ i think corsair. I dont remember i only remember that it was way way more expensive for this capacity. Still external or even regular hdds with 2tb capacity are way more cheaper then this solution (external disk are enclosed hdds so ...anyway). Either way that amount of data is never that cheap and never will unless u buy a second hand one, in the future maybe. So lesson not learned cause i knew all along that its a fake, but my sister now knows that she should trust me on computer matters. She thought she knew better. She failed. Hope that she learned her lesson and wont fall for this crap again. At least it was cheap and the capacity is decent and working. Also with aida64 it took me testing that stick only like an hour or so, test and verify all in all, 61hours and the like its madness.
My 64GB USB is reported like this, what's wrong? Warning: Only 59996 of 59997 MByte tested. The media is likely to be defective. 58.5 GByte OK (122871804 sectors) 2 KByte DATA LOST (4 sectors) Details:0 KByte overwritten (0 sectors) 0 KByte slightly changed (< 8 bits/sector, 0 sectors) 2 KByte corrupted (4 sectors) 0 KByte aliased memory (0 sectors) First error at offset: 0x0000000773c2d400 Expected: 0x0000000773c2d400 Found: 0x0000100773c2d400 H2testw version 1.3 Writing speed: 20.9 MByte/s Reading speed: 83.3 MByte/s H2testw v1.4
No problem, it's just a small margin of error. I'd say your usb is perfectly fine and is the 64GB it's meant to be as you can see 58.5GB came back fine.
@@ThePizzaByte oh shit thanks 😣😣😣 will this software work on hard drives too? Guess ill buy a 1tb hard drive instead... thank you so much for making ppl more aware.
If you buy sd cards from ebay there is over 80% chance you will end up with a fake regardless of how careful and knowledgable you are. Buying it from High Street outlets like currys tesco asda may cost you more but you will have (money back) guaranteed item that won't be a fake. By saving a few pounds why risk jeapordising your data or 'memory' of your child growing up
for 10USD , even can not buy a 64GB usb flash drive . I guess there are about 16GB are the real . The rest are the fake . if you always use that usb flash drive less than 16GB ,you will never find it is a fake .
UPDATE: Also when it comes to large sizes like 128GB+ Chances are they're much smaller. For that one I'd strictly test 32-35GB and no more. If that comes back as successful then try the whole size, but chances are a lot of them come back as 4GB/8GB/16GB/32GB Memory sticks never usually more.

Odds it it was a legitimate seller, but a scammer bought it, modified the 64 GB with a 16 GB, the got a refund. Seller refurbished it and resold it.
Thanks! I'll need this for some amazon cards I'm ordering!
Thanks for the video! I just bought a SanDisk memory card in a mobile store and turn out it is fake
My 1 tb micro sd has been going on average of 7.08 Mbytes/s and is at 88hrs 47mins and says
10.2 Gbyte OK
716.5 Gbyte DATA LOST/corrupted.
I was wondering why after around 8gb, every file before that mark would be written over with whatever new files were added. This video helped out a lot, thank you.
Oof, I should have said the moment you see Data Lost/Corrupted you may as well take a screenshot and end the test as the rest usually will result in a failure also. Instead of waiting for it to finish. Really wish fakes would disappear. If you are to keep the SD card be sure to delete the partition of the SD card and make a new one with a limit of 10GB, that way you can use it until it's real capacity.
@@ThePizzaByte the seller immediately accused me of breaking it by unmounting it improperly when I had files being written over. I knkw this issue is in no way related to removing an sd card prematurely. I am doing this and taking screenshots every 5 hrs to include in my email to remove any excuses he may try to give me to shift the blame. If he were an honest seller, I would definitely have done whag you recommended. I appreciate the rather quick response you gave!
Brilliant. Just what I was looking for. Will be checking all my sd cards. Finding my drone videos are a bit jitty
What these vloggers do not tell us is on how many hours does usb tester does the process. As of writing i tested my 2tb USB for almost 5 hours using h2testw but the bar does not even reach 1/8 of its status. This is a very tiring process but i have to wait for more hours I think provided I won't get bored of waiting...lol
I did pin a comment 3 years ago addressing this. I can promise you it won't be 2TB lol
Should have tried 128/256...
omg bought a 126gb sd card but only tested at 64gb (65536mb) and the verifying corrupts after 31.3gb..... does that mean that sd card is only at 31.3gb? i have trust issues
I'm in the process of testing my Aliexpress 128gb USB memory stick. I've already had problems with it. If you make a folder , the contents of the folder dissappear. Oh dear, I will tell you in 7 hours if the results are bad. But its only writing at 3.72 MB /sec
I should have said in the video, when it comes to large sizes like that, chances are they're much smaller. For that one I'd strictly test 32-35GB and no more. If that comes back as successful then try the whole 128GB, but chances are a lot of them come back as 4GB/8GB/16GB/32GB Memory sticks never usually more.
probably the greatest thing about getting fake drives is that the seller rarely wants it back, you'll get your refund, and you get yourself a free XXGB drive. I bought a "2TB" card, hoping that there is actually close to 256GB, but we'll see.
UPDATE:
The flash drive ended up only being 32gb. Lol yikes
I recently ordered 4 400gb micro sd cards on ebay for about $20. So far 2 have been tested and came back as 32gb micro sd cards. I got my money back without returning the sd cards but bummed they wasted my time.
@@bibbyshibby 1TB is not that recent , hell they have even dropped to $90 this cyber Monday
I encountered same problem. Can we stop sales website from becoming a place where fake products are sold? They should investigate and remove fake products to protect customers. If they do not do this, then they are accessories to the crime of cheating customers. Any idea?
just got a usb key looking usb flash from ebay it takes 12 hours to check it im excited lol
Just got one and too impatient to wait, was yours legitimate?
Rip vikingnorthgamer fly high brother
I’ve learned from my past mistake of trusting cheap flash drives online and so I lost a couple of files, but fortunately I recovered the data from the previous location so it's all good.
This time my mother bought an unbranded flashdrive online but didn't want it and so she gave it to me and I was shocked to see that it had about 900+ gb inside. Of course I don't believe that it truly has 900+gb inside and so here I am watching this video.
RandomPerson I buy 128GB memory card with reasonable price it’s still turns out fake , so cheap / not , It’s still a trap
What does it mean when it says the media is write protected? Does it mean it can’t even start the verification procedure?
testing the 256GB microsd card i just bought. 7GB and still running lol 8 hours to go
Edit: i just realized that it's 8 hours for writing and another 8 hours for verifying lol good luck to me
is there anything faster?
Hhhhh I also realize it already 😂
its because the fake memorycard is so slow......
I recently bought two 256gb EVO Plus from a new/small seller on eBay & tested one which took almost 38hrs to complete both Write+Verify combined using my old computer with USB2.0
Turned out, only 30gb was usable which meant it was a 32gb card.
It truly sucks that only a handful of us tested these cards & left negative feedbacks while the rest of the 100+ buyers were oblivious to the merchandise they received & just assumed they were real, leaving glowing positive comments, LoL.
This experience was a good lesson in learning how to differentiate the fakes from the real ones... yeah, I had to buy them again except this time it was with a big seller who I bought a new Galaxy phone from just a few weeks earlier.
And, it was more than just 2 as they were offered as a whole case Lot of 10 pieces... needless to say, it was a great deal & I now have enough to not have to ever worry about dealing with scam sellers any more =D
You'll find out way before then if its fake as you'll get error messages in the program.
Thank you for this! This is way easier to understand.
Is there software to change how big the drive says? So you can set it to it’s correct size
It's the drive itself telling your pc to read "128 gb" instead of it's correct capacity
The drive is the problem so just use a program to fill it with data and data overwrite
@@casmsfrought9956 but isn't it once you start "over filling" it's capacity that it goes haywire? I've had USB's bought from Big Chain stores years ago that I never checked and within 3 months all the folders turned into random strings of nonsense. The store wouldn't take them back even though they were the only one's who stocked that "brand" @KDStudios
i've seen a video where you could shrink your sd card to its real capacity
@@anngabrielleureta5214
Can you send me a link?
A very nice and informative video! Thanks!
Thanks a lot for the informative tutorial!
Mine i bought 128gb but it shows 134gb.. really suspicious.. turns out is a truly a fake. Thanks for the video 😊
Glad it helped, get that sent straight back. Although me and the missus had a right chuckle at the capacity being bigger when it's meant to be smaller. Funny find lol.
Great video, Thanks for that, I bought a 2TB USB stick on Ebay for around £5 and lost much of the 60GB that I transfer onto it even though I comes up as a 2TB stick!
How do I change it from 2TB to actual? Just rename it?
Thanks in advance!!
I've still not found a way to "hack" them back to their original sizes, but I just rename them to remind myself their actual size. Then they work fine so long as I don't exceed the real size.
i had also the same experience.. 1 1TB and 1 2TB flash disk (HP Brand)
My 64gb sd card says the media is most likely defective but it has 58.4GB OK so does it mean i can still use the 58GB? without getting my files corrupted?
Make a video about reprogramming its controller to its actual size.
Edit: Oh! Nvm! Found it right in your comment 😁
The Data volume section ies greyed out and wont let me choose all or any other amount??? I chose the drive properly first. It will only test 138 MB ?!! less than 1 gb out of 500 GB. SO now I just gona copy files to it to verify. It was not super cheap, price seemed right I just wanted to test before deployting.
My option for "Write + Verify" seems to be greyed out. Any solutions?
Okay so how do I know it's real? No errors? Finished the test at the end of mine it says 29.7 gb out of 32 gb sd card.
It’s probably fine.
Sometimes, some of the storage is not available.
The union soft external hard drive from the amazon is legit, i checked and i bought it and it said 250 gb but it gave me 230 but it takes some because the system requires it i think so it seems legit and the download speed is around 20mbps so pretty good for a small portable external hard drive
Tried a fake 512gb sd card.
after 64gb it's still counting.
Clone Samsung SD Card?
Thank you for your video !
Thanks! Im testing an ali express card 128gb micro sd card for $10. Seems too good to be true but im testing that now.
how's it going? was it fake?
So what you did you get ?
Infernox 2014 oof this comment is old. Yea I got a 32gb and my switch games kept getting corrupted. I ended up breaking it in half Bc it’s a useless piece of s***
@@CloroxBleachOfficial thanks
Thank you very much clear and quick
It instantly returns an error saying it’s “write protected”. Is this something I need to fix before running the test or does it mean it’s bad?
Edit: I had the switch on the physical card was set to lock. Don’t do that.
The SD card I bought is write protected and can't test it using H2testw :( . I have tried removing the write protection but all ways to no avail... how can I test this SD card I have?
Does the SD Card came w/ Adapter? if so there's a Tiny Switch to Unlock it
512Gb sd card used 6 and a half hours to write 190 Gbytes of data. 10 hours left. Is it fake?
Most scam drives have fairly small real capacities. I wouldn't test beyond 65 gigabytes. If Verify comes back at that point and stays it's still good, then it's likely that the rest of the drive is ok. Also a modern USB flash drive with a huge capacity should be writing at USB 3.0 speeds at least. Check the write speed while it's testing. A scam drive is more likely to be a slower, USB 2.0 drive.
Excellent dont know why they dont just put the amount its ment to be instead of ripping people off what are these pirates problems
I made the mistake of testing a full 500gb usb. Welp, 24 hours in and still writing.
Recently bought one that claims to be 2 TB (Has there been an actual TB USB drive before?) testing it now to verify what it claims to be but I doubt it is.
Yes they do exist. However, just test only 70GB (70000MB in the program) first. If it loses ANY data, it's fake. Or if that comes back fine test 130GB, then 270GB etc. Just to be sure. Testing 2TB will take forever.
@@ThePizzaByte Yeah, it took 12 hours just to reach 200 gb before a blackout happened and I'll try testing at 70 gb first and make my way up.
My father bought himself a 4 TB HDD for 24€ on wish, lmao, I told him it's 100% fake but he doesn't believe me..
lol
I bought fake 128GB Toshiba SDCard but it says 134GB how can i fix it or shrunk on original storage 😭
Open Disk Management (Search for partition into the start menu) then delete the partition of the SD Card and create a new one with the actual storage capacity it has. HS2testw will let you know how big it is when finished testing.
funny you dould just copy paste files in there until it gets filled up and get done faster
I just buy a 1tb microsd card for fun (RM23 only)plan to make a video aswell
but when running test. after 2days. it show 62 hour left. and I dont see error yet. now tested 260gb... l going to left it run for another 62 hour...
btw the writing sppeed at 3.37mb/s == dame slow
I also bought 512gb OTG for my iPhone at Shopee for like rm38. Also testing it using H2testw, now it’s writing at 210gb & 5 hrs left. Assuming verifying will take another 12hrs I can do some laundry 😂 but the speed is faster, aroung 15.8mbps
I ran this and fakeflashtest on an SD card I got from eBay that was supposed to be 128GB (already got a refund because it arrived two weeks late, the seller emailed me directly and their account was deleted from eBay).
They both say I've got only 117MB of space, and that the rest is corrupted. However, I put a 900MB video file on it and it ran all the way through without errors.
I'm so confused :(
I've bought a 32GB sd card, which appeared to be fake, It has 114 mb storage only! and yes i can fill it up with a movie of 1GB but after a while i get an error message while playig it. Also pictures are not shown up in the gallery app saying "cannot generate thumbnail". I thought something was wrong with me phone but I bought a fake ass sd card
You should restart your PC and test it again.Then, you will find that "900MB" video has erros.
The reason this happens is that the SD card will just rewrite itself continuously when it runs out of space on these fakes. So to your PC it's copying fully, but if you tried to play it back it would either be completely broken, or highly corrupted. When these programs write the data, they generate a hash signature that's verified when the data is read back. Essentially making perfectly certain the data contained (fully filled) on the SD card isn't corrupt. Another helpful tip is noting the write/read speeds when the test operates. Especially for higher end cards that have ~90+MB/s read/writes. If it's only giving you 2MB/s on linear reads/writes it's probably fake.
Hmm, 256GB EVO SD Card, currently writing, 4 hours - on my gaming computer i7 { kick ass computer }
I bought a 2TB external drive for £30 from eBay to store recovered data from a genuine 1.5TB Fujitsu drive. I just copied across about 500Gb. Shit, Shit, Shit. It only took 30 hours to recover.
2 TB flash drive, but this prog does not work with it
Just partition it to 128gb and test that. Chances are its tiny.
But can u now use that 4gb without problem?
Maybe making a 4gb partition of it?
Yes if you’re willing to keep it, but always get a refund if you can. However if it’s too late then yes just partition it as the stated “OK” size
Does this test erase the contents of the flash drive being tested?
KINDA LATE, BUT YES...
welp, rip the 256gb card dudd i bought. i ran the test on it, it took over 16 hours [mostly to verify] and unforunately, a power outage restarted my PC in the middle of it. but from my recent screenshot of the progress- it was 68kb OK and 147.5gb _[and counting]_ DEFECTIVE... that's more than ha l f... way more than enough evidence to prove it fake. i think it was a 16gb card because i was able to fit around 12gb of stuff on it before it started bugging out
;/ bummer
I bought a Blue Wave 256gb sd card off Wish. Its given me nothing but problems. It freezes up my phone, it deletes my music and corrupts my vdos so they are unplayable! I dont believe it is 256, its prob not even 128, maybe its 32? You get what you pay for.
total rubbish, i bought a few of these ans none of them worked, couldnt get a refund , buyer beware
thanks very helpful
thank you
Thanks buddy
Does the app not tell you the read write speeds though?
It will, you can see it one the top left, right above the text box that states "Warning: Only ******** of ******** Mbyte tested.
I got a 2TB external hard drive
Im doing it with a usb stick with 2tb and with 6,5 MBs😂 its been 40 hours and it testet 1tb now, now i have to wait the other 40hours😂
Does it format the usb before testing it?
no I don't think so
@@TheAndrexzKINDA LATE, BUT YES IT DOES....
How can you test to ensure the memory card is the actual brand you purchased ? Maybe you buy a 16gb card, it is 16gb, but it might be branded as something it is not ??
Honestly, unless you're selling the items it really doesn't matter.
All that matters is that you're getting the speeds and the capacity you pay for. I hope this helps.
Thankfully this tells you the read/write speeds and the capacity. Google the speeds your card is supposed to be at and also check to make sure you're using USB 3.0 so you know you're getting the best possible speed.
SD Insight tells you but you need to use an android to get that app.
thanks...
after 3:54 in the video, what's the point of returning and further "examining" this terrible fake storage? haha

What Happen If You Upload File That's More Than The True Value?
data will be seen as if its written but when you want to read it its lost. errorrrrr
u can do the same test with aida64 btw, i bought a 2tb, well not me i know its a scam, but my sister insisted she knows someone who bought a 1tb usb stick and everythings great, i said to her probably its great with a few files that work, rest is lost, she insisted on buying it for me for 4€ so i said what the hell, itll be fake anyway. Did get it, tried it, it showed 1.9tb free, i said sure, copied a few files and was ok. Tested in aida64, first test showed a quick 753gb somethign, i was like, hm could it be the capacity is well not 2tb but at least 750gb is still good enough for this cheap. Well no, turned out, when i performed the write test and verify, well it showed only 15gb could be realistically wrote on this drive, but i think well its still ok for 4€ but not near 2tb, then i went online searched for 2tb flash disks, well the cheapest is like for 200€ and its a disk not a stick (i dont think they are the same) i think brand is Patriot and the most expensive on that list was for 330€ i think corsair. I dont remember i only remember that it was way way more expensive for this capacity. Still external or even regular hdds with 2tb capacity are way more cheaper then this solution (external disk are enclosed hdds so ...anyway). Either way that amount of data is never that cheap and never will unless u buy a second hand one, in the future maybe. So lesson not learned cause i knew all along that its a fake, but my sister now knows that she should trust me on computer matters. She thought she knew better. She failed. Hope that she learned her lesson and wont fall for this crap again. At least it was cheap and the capacity is decent and working.
Also with aida64 it took me testing that stick only like an hour or so, test and verify all in all, 61hours and the like its madness.
i bought a 2 TB usb for 2 dollars on wish.com , is there any faster way to check?

If you buy sd cards from ebay there is over 80% chance you will end up with a fake regardless of how careful and knowledgable you are. Buying it from High Street outlets like currys tesco asda may cost you more but you will have (money back) guaranteed item that won't be a fake.
