Howdy -
I have a problem with my hard disk sticking. On power up, after a brief
delay, the disk hardware does a rapid series of seeks (it's always done
so), presumably to generate enough vibration to start the disk spinning
if it hasn't done so already. Well, my disk is old, the manufacturer
has gone belly up, and the disk has begun sticking so regularly that I
no longer have the screws in my Mac case, so I can remove the cover and
jar the disk when this problem occurs.
I would like to disassemble the drive (to minimum degree possible) and
lubricate the spindle, but my natural caution tells me that there are
many ways of doing this, but only a subset are correct. Does anyone
have knowledge in this area they can share? My gut impulse is to drop a
few drops of 3-in-1 oil where it seems best, but my gut impulses have
gotten me into trouble on more than one occasion. Any thoughts?
Thanks.
- Scott

Your natural caution is well founded. The only place that a hard disk should be disassembled is a clean room, as in the type of room the put space sattelites together in, these are very very clean. Also the lubricant is very special, definately not 3-in-1 type stuff. My suggestion: back up the disk on floppies ASAP and get rid of the drive. There are places that can repair drives but they are expensive and only have 90 day warranties. A new drive is really the only option open. AFTER you get a new drive, and have backed up the old one, then you could play with the old drive. I know that I would love to play around and see the inner workings. Come to think of it I think that I will pick up an old $5 drive at my next ham-fest.
