Make sure all pins and sockets are clean and tight..
Is the CD ROM seen by System Profiler ?
What about termination ?
Pins and sockets appear clean and are tight. ASP does not see the drive. I have not changed the termination on either drive, so they should be at the factory settings.

what about startin from the drive !??? with any disc just to see what happens - and yes some pram I experienced going bad resulting in a non functional cd, and also errors in hds, and external cables, so take all extras out and aswell the main hd and try starting from a cd ?
How do I start up from a CD if one drive won't open and the other won't see any CD?
did you rebuild the desktop ?
Yes.

I fear the Mac in some cases just won't tolerate a non-Apple-ROMMED CD.
They're both the original drives, with Apple labeling.

Either drive may not be receiving the proper signal from the board to activate the eject sequence. Take a look at the internal SCSI cable and pull it off its motherboard connector, give it a blast of contact cleaner, reattach and try again. Humidity/oxidation of tiny electrical contacts is suspect when devices that worked before storage fail after reactivation.
I will get some contact cleaner and try this.

If at all it could be extension trouble, we can send you relevant uncorrupted ones by email... (since you can't use the CD to get originals).
I hadn't thought of an extension problem. I do have an old CD burner that reads CDs (but very slowly, so I'd prefer a working CD-ROM drive rather than rely on the burner), so I can get fresh extensions from my system disks.
May be a power supply problem?
Can it be a power supply problem if everything else (HD, Jaz drive, etc.) is working?
I have a Matshita drive that has run on a non-apple extension ok (CD-ROM Toolkit). If the extension is the problem, I can send D.F. Manno this or the original from OS 9 or ferret out the one from 9.1 (probably the same).
I'd appreciate it if you could send that to me. It's worth a try.
power cable (there are spares I think in the 7500)
Inside the computer itself? I didn't see any when I was in there.
Anyway, CD drives are cheap so maybe get a less than $10 one known to work and go from there... You have put thru diagnostics like Norton's
TechTool Pro found some incorrect file dates, but nothing else
battery OK
Battery checks out OK.
been doing anything new lately like with RAM?
Nope. The only thing I've done inside the box is switch the CD drives.
From: Ken Grunke <[EMAIL PROTECTED]>
Do you have a CD driver enabled in the Extensions folder? Like "Apple CD/DVD Driver"?
Yes, of course. Version 1.4.4.
