CDROMs are recognized and are mounted without problems when running knoppix from the CD, but on my hd install with this particular version (that uses kernel 2.6.11): Code: # mount /cdrom mount: /dev/cdrom is not a valid block device Same thing for my slave CDROM drive. I believe the relevant fstab lines are fine (they worked for me in the past): Code: # cat /etc/fstab \| grep cdrom /dev/cdrom /cdrom iso9660 defaults,ro,user,noexec,noauto 0 0 /dev/cdrom1 /cdrom1 iso9660 defaults,ro,user,noexec,noauto 0 0 So I checked dmesg, and what's on /dev/cdrom and /dev/cdrom1 (I have two CDROM drives): Code: # dmesg \| grep CD hdc: HL-DT-ST RW/DVD GCC-4481B, ATAPI CD/DVD-ROM drive hdd: HL-DT-ST DVDRAM GSA-4120B, ATAPI CD/DVD-ROM drive # ls -l /dev/cdrom /dev/cdrom1 lrwxrwxrwx 1 root root 8 Apr 17 14:13 /dev/cdrom -> /dev/hdc lrwxrwxrwx 1 root root 8 Apr 17 14:13 /dev/cdrom1 -> /dev/hdd At this point I don't know what to do to get the CDROMs working, and some help would be most appreciated! Thanks in advance.

I tried mounting both data and music cds; it didn't make any difference.

Are you using a kernel you compiled yourserlf? __________________ serzsite.com.ar "All the drugs in this world won\'t save you from yourself"

You're right, I just wanted to see if I could mount them and read its contents. In short, the problem doesn't seem to be related to the type of CD; somebody asked me to check whether it's possible to communicate with the drive. So I did

Code:

# eject /dev/cdrom1
eject: unable to open `/dev/hdd'

No, it's the 2.6.11 that knoppix 3.8.1 comes with, which I installed with knoppix-installer, and choosing the "debian-like" installation option.
