Kernel 2.4.19-rc1-ac3. I tried the -no-pad option. I also tried readcd dev=2,0,0 f=/test.iso, that failed also. The latest cdrdao seems to read and make good copies though. from /var/log/messages: Jul 13 07:50:14 251 kernel: scsi2: ERROR on channel 0, id 0, lun 0,CDB: Request Sense 00 00 00 40 00 Jul 13 07:50:14 251 kernel: Info fld=0x50698 (nonstd), Current sd0b:00: sense key Medium Error Jul 13 07:50:14 251 kernel: Additional sense indicates Unrecovered read error I will test later with some other media, a different build of cdrecord, and I will run a cleaner through the drive.
