The drive's wedged so tightly that it doesn't respond to the button on the
cd-tray drawer (it does, however, respond to the paper clip, but that fixes
neither the eject command nor the drawer button). This usually happens after I
have some mishaps mounting and unmounting the drive. I can recover the drive
by rebooting, but what, if anything, can I do short of rebooting to recover the
drive?
From a mechanical point of view, this sounds like a bad servo or
actuator motor in the drive. Is it old? New? Is the drive sluggish to
eject the drive, does it feel stiff, like something might be grinding on
the tray itself? Do you have kids that like to hide small things in
really neat new places?
