I got a bit further with seeing my old SCSI-Periphals on the external SCSI bus connected to the sym0 (ASUS SC-200 Interface). I can dd one of the disks connected there (/dev/da0) completely (2GB) But I cannot dd if=/dev/cd0 of=cd_dump Doing this, I’m getting $ dd if=/dev/cd0 of=cd_dump dd: /dev/cd0: Invalid argument 0+0 records in 0+0 records out 0 bytes transferred in 0.000199 secs (0 bytes/sec) $ What’s wrong? /dev/da0 and /dev/cd0 are both character devices. I can well cat /dev/cd0 >dump . — Christoph
