My ext Apple SCSI CD-ROM (it uses a jewel-case-type thing [a bezel?]) drive is not reading CDs. It is connected to my Quadra 700 (running 7.5), and when I inserted a burned CD-R, it seemed to read the CD (the orange light went on), but the CD didn't mount on the desktop. I tried a Macaddict CD and it just spit it out.
Could someone tell me what's going on?Wonko The Sane

Did it work before?
I'm not sure the old caddy loaders are capable of reading CD-R or RW media because the reflective characteristics are not up to the same spec. Try an System/OS CD from Apple.jt  ™.

Yeah, what Trash said, particularly if it's a 150e (1x) drive, I doubt it'll read CD-R/RW discs. ~Coxy - Leader, Tactical Operations Unit

your "bezel" is a caddy.I have a caddy cd rom drive. I burnt a cd using my external cd burner for reading & my internal cd caddy drive for recording from. I am currently listening to the burnt cd(Steve Harley & Cockney Rebel). My cd caddy drive I believe to be 2x. What I advise is that your mac is not seeing the drive. My mac wouldn't "see" my cd burner. Then I changed the scsi id from 6 to 5 & suddenly all was well! try changing the cd drive's scsi id. have you tried mounting the drive? through some utility software? shaktiman Quadra 840av 128MB ram 2MB vram cd drive(caddy),1 caddy!:-)1.44 floppy drive,inject :-(1.2 gig drive

Methinks your PSU could be starting to give out. I have the exact same drive as you, and it sometimes needs to warm up before it will work properly, when in the external case. If i don't let it warm up, it will just do what you mentioned in your post. However, if i put a PC power supply next to it, connected to the drive, and power on, then the drive works great. Try mounting it in another SCSI case or something.-------------------------- "I keep my friends close, but I keep my enemies closer" - Unkown Warrior maclover5

It did work before. I'll try leaving it on for an hour before I use it and see if that works. How do I change the SCSI ID?Wonko The Sane

I tried it again, and I realized that my Q700 had a bad Pram battery. I thought that could be the cause until I tried it on my Duo 280c (running 7.5.3). At first, the Duo recognized that the drive was connected (SCSI ID 3, if that matters) but it didn't see it as a CD-ROM drive and treated it as a floppy, it tried to initialize the disk. It just wouldn't recognize the CD (which was burned in OS X.2, if it matters). Then the drive just turned off by itself for a few minutes, I had to toggle the power switch a few times to get it back on. Then the Duo didn't see a disk.
The power supply is messed up, but how does that explain the Duo's weird reaction to being connected too the drive?

If it's terminated the resistors aren't getting a full 5v and/or the SCSI Controller IC in the drive is wigging out on the crappy voltage?Dunno, but STOP running it on that crapped out PSU! jt ™.

Is this the really early CD-ROM drive (matches the 40SC tape drive and the big box II series) or the later Sony drive? If it's the latter, I'd also consider swapping out the actual CD-ROM drive for a later Apple-ROM drive (300i or 600i). Lots more convenient.<<<john>>> |

It's an early, boxy drive. What kind of PSU can I put in it?Wonko The Sane

One that'll fit?  . . . on a slightly more serious note . . . any external case you can lay your hands on has got to be better than that Long@$$ boat anchor box, if you haven't got more than one to use stacked up, use the cable/ID switch hardware and install it in the next PC MiniTower you pass in the street or watch for a dead external case and move it.Meanwhile lay a bare PC PSU on top of it and run the cable/connector inside until you get a better drive or a new box! jt ™.
