Data CD's seem to automount without any problems.
The output of the mount command is:
mount: block device /dev/hdc is write-protected, mounting read-only
hdc: command error: status=0x51 { DriveReady SeekComplete Error }
hdc: command error: error=0x54
ide: failed opcode was 100
end_request: I/O error, dev hdc, sector 64
isofs_fill_super: bread failed, dev=hdc, iso_blknum=16, block=16
mount: wrong fs type, bad option, bad superblock on /dev/hdc,
or too many mounted file systems
Regards
Simon
