Diagnosing CD-ROM problems

[EdLeafe]

I recently had the power supply on my server die, and got it replaced at a local shop. Everything's working fine except for the CD-ROM drive. It refuses to read anything! When I try to mount the CD, either using the desktop icon or the usermount utility, I get the message "medium not found", even with perfectly good CDs in the drive. The tray open/close mechanism is working OK, so I know the drive is getting power, but something's obviously wrong.

Can anyone suggest some diagnostic utilities to test it with, or any other tips on figuring out what's wrong? I really don't want to have to take the server down again if at all possible.

There is a good chance the CD took a power spike when the power supply went out and blew the laser.

At the hardware level, I am afraid you will have to shut down the server to really diagnose it, sorry I don't know of any utilites to test with.

If you have a standard CDROM drive in the box along with the CD-R drive, take out the CD-R and put the CDROM in its place, see if it works on the same channel with the same power connections. OR, if you have a spare CDROM drive try it in the same slot. If another drive works in the same slot on the same channel with the same power connector , you can bet the drive is bad.

Thats the trouble-shooting I would do, but I tend to agree with the previous post, The laser is probably bad.

Sorry scratch the ref to CD-R, I have CD-R on the brain for some reason.
