wrong fs type, bad option, etc. etc.


having a bit of trouble getting an atapi (scsi emulated) cdrw/dvd combo drive mounted. keep getting the following error:
Code:
root@slacktop:/home/lyceum# mount -t iso9660 /dev/sr0 /mnt/cdrom
mount: block device /dev/sr0 is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/sr0,
       or too many mounted file systems
i have loaded the ide-scsi module, my lilo.conf file contains the line: append = "hdc=ide-scsi", and during boot it seems to be added correctly. no error messages in dmesg output except for alsa (another problem for another day). my fstab is as follows:
Code:
/dev/hda5        swap             swap        defaults         0   0
/dev/hda2        /                ext2        defaults         1   1
/dev/hda6        /usr             ext2        defaults         1   2

/dev/sr0         /mnt/cdrom       iso9660     noauto,user,ro   0   0
/dev/fd0         /mnt/floppy      auto        noauto,user      0   0
devpts           /dev/pts         devpts      gid=5,mode=620   0   0
proc             /proc            proc        defaults         0   0
the command: cdrecord -scanbus gives me:

i checked /proc/filesystems and it contains iso9660, also the command: eject /dev/sr0 successfully ejects the cdrom. i've tried both audio cd's and dvd roms. i'm perplexed. any ideas?

thanks in advance,

lyceum

p.s. i have had this cdrom working correctly in both redhat9 and fedora core 1, currently running slackware 10.

edit for spelling

Are you sure your cd entry shouldn't read /dev/hdc or /dev/cdrom?

My fstab entry reads:
Code:
/dev/cdrom  /mnt/cdrom  udf,iso9660  user,unhide,automount,kudzu,ro  0 0

it actually had /dev/cdrom in that entry of fstab, but i'm using scsi emulation and /dev/cdrom is simply a symlink to /dev/sr0 which is the scsi device that has been associated with the drive. i changed it during my investigative stages, but wouldn't make a bit of difference as is.

Try /dev/scd0.

BTW I'm assuming your trying to mount a data CD. You can not mount an audio CD.

If you are trying to mount an audio CD, it won't work. Mounting is for any media that has a filesystem...
