Hello managers,
I'm trying to use a third party CDROM drive (Pioneer CD-ROM changer
DRM-624X). I could mount and read OS distribution disks and
ISO9660 disks. However, I could not mount Software Product Library
nor Documentation Library. Is it possible to mount these CDROM's
on DRM-624X? (Actually I'd like to keep Documentation disks online
with this changer.)
[device files]
# file /dev/rcd0
/dev/rcd0: block special (8/20480)
# file /dev/rrcd0
/dev/rrcd0: character special (8/20480) SCSI #1 RRDxx disk #96 (SCSI ID #4)
[CDROM's that can be mounted]
