My neighboors just gave me their dead CD-RW drive. It woudl probably be easier for me to just buy a new one, but I want to get this one working. So first thing I do of course, open the sucker up. Please don't tell me to check and make sure my drivers are right because it's a bloody plug and play drive. Oh yea, the problem is that the drive doesn't see a cd when you put one in. So back to the point, I cracked the sucker open. What I have figured out so far: The lense is clean. The drive tray motor is functionally properly. The cd spin motor is working fine. The motor to move the lense is operating without problem. I put the drive in without the top on so that I could observe what it was doing. When the tray goes in, the lense shows a red laser, and if there's a cd, it will spin the cd. The lense seems to be sliding back and fourth without problem.
