cannot mount cd-rom


Hello Every1!

have some trouble mounting my cd-rom. By today it worked perfectly but from today i get messages

"/dev/hdd0 is not a valid block device"

when i try mount

"/dev/hdd0 /mnt/cdrom" as root. Same for /dev/hdd1 /mnt/cdrom or /dev/hdd /mnt/cdrom.

My cd-rom is recognized as hdd, here is dmesg messages:

"Probing IDE interface ide1...
hdd: TEAC CD-W552E, ATAPI CD/DVD-ROM drive
.
.
.
ide-cd: passing drive hdd to ide-scsi emulation
.
.
.
"

Thx for help.

So I suppose you have the hdd=ide-scsi reference in your boot manager. Then you should use the SCSI device /dev/scd0 and not /dev/hdd unless you have a symlink from hdd to scd0.

Trying to mount hdd0, as you wrote, is wrong anyway. Hdd0 would be the primairy partition on the cdrom, which doesn't exist on a cd. Second, try not to use /mnt/, this should be used only occasionally, e.g. for mounting iso's with loop.

Either try:
mount -t iso9660 /dev/hdd /media/cdrom
mount -t iso9660 /dev/scd0 /media/cdrom

Also, when you add this to fstab, check your permissions on the device node for the users. You could create a cdrom group and add users to this group. Chown the node as root.cdrom.

Other questions - are you trying to mount an audio CD? If so, mounting will fail, because music CD's lack a valid file system. Also, is the data CD actually in the drive? You will not be able to mount an empty drive, and if things worked yesterday but not today, maybe you just ejected the CD last night and haven't put it back in yet today -- J.W.

when i try

mount -t iso9660 /dev/hdd /media/cdrom or
mount -t iso9660 /dev/scd0 /media/cdrom

i get the same again:

mount: /dev/hdd is not a valid block device
mount: /dev/scd0 is not a valid block device


No i'm trying to mount a fully loaded CD-rom and NOT an audio CD!
