well, i gave mine a shot... 1.2gb maxtor hard drive i found laying around. might as well have been trash as far as i was concerned, so i wasn't worried about damaging it.
they're not all that delicate. i didn't bother with the humidified air. all i did was have a piece of saran wrap (sp?) that i put over it once i took the cover off. after noting the saran wrap actually touched the arm (the arm was above the outer case sides) i simply took the saran wrap off, and let it sit open. i plugged it in, let it do it's thing (sitting on top of my mini-fridge) and it worked great.
"well that was easy" i thought. so i scavanged about and found the plastic box/cover off an old thermaltake ram heatspreader. i cut the plastic to fit the hard drive, and placed it over the disk itself. fired the puppy up...still all going great.
next i drill holes in the plastic where the screw holes were in the hard drive itself, then zip-tied the plastic cover to the hard drive. now here's where the problem occured. somehow (dont ask me how) one of the tiny tiny magnets on the top arm ended up flipped over (it was pushing away from the disk, making the end of the arm bend up slightly from the disk). this caused the disk upon bootup to click back and forth, but not work anymore.
well, i ripped off the plastic cover and attempted "brainsurgery" on the magnet, but was unable to get it properly back in place. so the drive was shot. i still cant figure out how the magnet flipped while it was under the plastic cover.
the final stages involved me completely disassembleing the platters, arms, magnets, etc... was fun tearing it up, altho i must say it would have been better to have it functional and open.
ahh well, i'm off on a quest to find more old hard drives from friends to re-attempt this feat.
