I have a Pioneer DRM624X connected to a Compaq Deskpro 466 through a BusLogic BT747 SCSI host. Dmesg shows individual cdN (cd0-cd5) for all discs in the magazine (6). However, upon' mount_cd9660 /dev/cd0a' or 'cat /dev/rcd0a | hexdump -C' the response is "Operation not supported by device" Paul Apprich
