Issue a "SHOW DEVICE" at the dead sargent and post the output.
Well...this could explain a bit: I was burning at 24x and throwing those
discs at a 12x drive.
:rolleyes:
That generally has no correlation whatsoever.   What's important is
whether
or not the CD-rom can read the recordable media you're using.   Some
record-
able media works better than other in older CD-rom drives.
Hey, I haven't touched CD-ROM stuff in awhile! ;)

You need a refresher...

BTW, the drive you have installed, is it jumpered for 512 byte blocks???
I'm not even seeing a jumper for it on the drive.   Drive is a crippled
Apple CR-507-C (Hey!   It's the only working SCSI CD-ROM drive I have!)

I wouldn't be surprised if your problem turns out to be related to the block size. DEC machines wants disks (including CD) to have 512 byte blocks. A majority of CD drives do 2048 byte blocks. Not compatible.

I think I have several 512-byte sector drives!   None of them SCSI...

The drive burning the images is 2048-byte...that'd explain the problem.
