Maybe, maybe not... Does it still work reliably (in other words, could it
be a headcrash?)

I've never done this, but I can possibly give you some problems you'll
have to work arounds
1) You will probably have to remove the platters and heads. Apart from
the obvious problem of contamination, you also need to keep the alignment
precise. This is something that's not necessary when the drive is first
assmebled, it's assembled, and _then_ it's low-level formatted. But you
need to be able to read the existing data on the drive, right?
2) Dismanting the motor to get to the bearings is going to be
non-trivial, if it's even possible. I would assume it's assembled on a
press, it may not be possible to get the parts to separate again without
3) A few weeks back we had a thread where somebody stated that the
lubricant in hard disk bearings was critical, as it must not creep over
the platters (most lubricants do).
