I recently restored a Mac PowerBook 160 that was apparently dropped before
it made its way into my hands - the hard disk won't even spin up, several
of the screw mounts were sheared in the lower case and the floppy guide
rail had jumped its track entirely. The head was flopping around loose
inside the drive. It took a bit of fiddling, but I remounted the guide rail
and reassembled the drive - worked the first time. Now if only I had a
2.5" SCSI drive to drop in this thing, I'd have a portable rig for dumping
my QuickTake 150 digital camera.
