Problem in mounting CDRom


When i am trying to mount the CD Drive the following error is occuring


mount: wrong fs type, bad option, bad superblock on /dev/cdrom,
or too many mounted file systems
(could this be the IDE device where you in fact use
ide-scsi so that sr0 or sda or so is needed?)

I tried many CDs and also changed the drive once

Any idea???

Do you use an scsi CD-Rom Drive?

If this is so, check if you have a line in your lilo.conf

append="hdc=ide-scsi" (if hdc is your driveletter)


Then check your /dev/cdrom device, if is most likely a symbolic link to
the generic device, type ls -l /dev/cdrom:

lrwxrwxrwx 1 root root 8 2003-12-23 16:04 /dev/cdrom -> /dev/sr0

Like here, it points to the scsi-device /dev/sr0

(you get the device names out of "dmesg")

Be sure that you chmod your permissions that you can access it as a user if you need to.

hope that helps,
