The gears are fine.  I thought I had purchased a working CD-rom2 that only needed a new middle gear but the disc would not even spin.  Something else is up and I'm too broke to send it out atm.  Just dissapointed...

Sounds like a laser issue then...or possible the spindle motor. If the laser doesn´t see the disc, then it doesn´t spin up. Check and see if laser light is bright, if its only faint or hardly any visible, then the laser might be dead.

??? laser don't see the disk??? how would it see it if its not spinning. Unless it's just looking for a reflective surface at first. It's always been my understanding that once the laser breaks the midpoint switch it will spin the disk to start to read it. I may be wrong???

Upon power up the laser seeks to the middle until it trips the limit switch.. at which point it powers on and looks to see if a disc is present, if it sees one it spins it up and then tries to read the TOC.

Interesting to know, I would think it wouldn't know a disk is in there till it could read something, and to read we all know it needs to be spinning. Nice bit of in there :-)
