Any ideas on what to try to bring back a failed MFM original Seagate (It's been a while since I've opened it up. I think it's probably ST-225, it's a 20MB Seagate) hdd?

The drive spins up but fails during boot. (Last I remember. Will have to drag it out again and verify though)

It would be nice to get my old data off of the drive as it has some of my old files on it that can't be replaced.

I remember these drives didn't park during shutdown so the read head could get "stuck" (correct me if I'm wrong). Should I open it open and verify that the head moves freely?

If all is lost, any recommendations on an 8-bit compact flash HDD replacement (if they exist).

Thanks!

Finally got around to dragging out the XTs from storage. Looks like my Seagate full height drive is lost to the sands of time. The drives that are in my two XTs are both Miniscribe drives (one newer than the other).

I was able to get them to fully spin back up and boot! The encoder that moves the head is accessible from the side of the case and (even though it's labeled "do not spin") if you spin it slowly, back and forth, it looks like it unstuck the head. Also the platters are able to be spun from outside as well so I gave them a little spin as well.

To keep them from re-sticking, I heard of this stuff called Tri-flow Superior Lubricant that's like a teflon based liquid lubricant you put a few drops on the encoder bearing. I went through with this and so far, haven't had any issues with the drives not spinning up.

One drive appears to be working perfectly again. The other drive was working okay but started getting weird (would spin up but then stopped booting into DOS) before the power supply decided it didn't want to work anymore. (No power when the switch is flipped.) That second drive that stopped booting had the nice volume name of "SH*TDISK" so I'm guessing it was giving me a headache 17 years ago when I first put it in that computer...
