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. Johnny 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. No. The writing is fine. You can write the data on any drive... You need to read it on a drive that do 512 byte blocks.
