The scratching sound comes more from the lack of the cover. It causes air to be improperly channeled under the heads and they sink lower towards the platters surface.
what is the problem with the second one (1m9sec), I have a ST251-1 with exactly the same behaviour and noise and would like to get some data off it. electrical or mechanical problem?
I have some Seagate ST-251 drives 2 in good shape and two that need help. One has damage to the flex cable at the front of the cover in 7 conductors and I may be able to do something with it. The worst one was given to me without a cover and the top head ripped off. It can run on 5 heads, but still has significant damage that it is only useful as a demo drive at 20MB. All my drive have good logic boards and mechanicals.
Damaged platters? The whine is coming from the bearings inside the spindle motor. That and when the drives are open the airflow is not channeled properly and the heads do not lift as far off the platters.
MarWi16A I think these hard drives are absolutely gorgeous machines it's nice to see what our current hard drives have come along since the 80s and 90s I wouldn't mind all three of these hard drives just to have them Idle for no reason maybe just sit there and play with their heads move the heads back-and-forth pretend to read right data
rallyscoot I don't know if he even tested them... because all I see them doing apart from the second hard drive which had a dead stepper motor all they were doing was the seek test
VideoTape i'm gonna try to collect all old hard drives computers whenever possible I don't care if someone says you should only put your money in the things you need to survive and yada yada whatever
I would be interested in this hard drive because of its sound. How much money would you give? It's okay if you can't copy data or install an Operating System with it anymore. it resembles the sound of my favorite trolleybus. Do you have a Messenger
The first one seems fine, but the third one definitely has the end of the platter damaged, as the scraping noise signals.

@@AiOinc1 I'd assume that greatly increases the chance of a head crash right?
@@cdos9186 the sound you're hearing is the heads contacting the disk, that *is* a head crash by most definitions
#1 Bad heads / head amp / flex cable
#2 Bad stepper / driver
#3 Head crash
I'm pretty sure this was the hard drive in my 386 when I was a kid in the 90's
They were extremely common in their day.
1:24 Ouch!

any extra seagate at-251-1 hard drives that work im interested in some

They all sound like they have damaged platters, so the heads are likely damaged as well.
2:22 sounds like an old tractor!

@@AiOinc1 Then why does the sound come and go depending on where the heads are?
@@videotape2959 Platter air drag is much more dispersed at the edge of the disc.
it looks soo much different
im scared of the sound it makes
i totally understand you :-)

Do you know why its dead? Have you ever consider to reflash the eprom? I guessing these eproms will loose their contents over 25+ years..
rallyscoot I don't know if he even tested them... because all I see them doing apart from the second hard drive which had a dead stepper motor all they were doing was the seek test
the first drive i heard heads touch platters so that one is dead for sure.
2nd one maybe bad PCB..
3rd one head crash. so i dont think either of them are fixable..
Christopher Ryan oof
Interesting, black colored platters
They just look black in the video, they are brown in reality. They change from light color to brown the more in the middle
Sounds like a old aeroplane
I have an ST-251-1 and a -0.
The -1 was much faster!
If you swap the PCB from the first drive with the one from second, the second could work.
I already tried to do that, but it didn´t work :-( they are all dead
MarWi16A That is really sad, I love these, but I never had any of them...
Krivulda could replace the head stack
You better get one now before they all get destroyed.

I would love to use these just as noisemakers inside a couple of my older desktops
Some st 251 with high prices on ebay
