[PLUG] CDROM making me crazy
|
Help!
I've tried everything I can think of to fix this and _still_, I get
the following message when I try to mount the cdrom device:
mount /mnt/cdrom
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?)
Here are the details:
Machine: Pentium box, SCSI HD (NO IDE drive) Teac CDROM on
secondary IDE as Master (/dev/hdc). Have tried two
different CDROM drives and two different cables.
The BIOS can identify the CDROM on boot so it appears
to be connected properly. We cannot move it to the
primary IDE or it will conflict with the boot-up of
the SCSI drive :-(
OS: e-smith 5.6 (based on Red Hat 7.3 IIRC)
Situation:
We had a working box (don't most vexing problems start out
this way?) and we went to install a Travan tape drive on the
secondary IDE as a slave device. When we booted the bios would not
see either the CDROM or the tape drive. We tried switching the master
and slave relationships and there was no change.
We decided that the travan tape drive was bad and went back
to the SCCI DDS-3 drive that was there before (don't ask :-P )
Now, the BIOS sees the CDROM, the OS appears to see the CDROM
(it's in dmesg like this: "hdc: CD-532E, ATAPI CD/DVD-ROM drive")
but no CD-ROM can be mounted. I know that it's not on hda|hdb|hdd
since I get the "not a valid block device" message. We've tried
several CD-ROMs - factory and CDR's with identical results.
Anybody have any ideas? I suspected that one of the times I booted
the box with the Travan installed that the kernel must have changed
something but I have no idea how or why it would do that or how that
could influence the subsequent boots.
Here, by the way, are the commands I tried as well as the
contents of fstab and mtab:
mount /mnt/cdrom
mount -t iso9660 /dev/cdrom /mnt/cdrom
mount -t iso9660 /dev/hdc /mnt/cdrom
mount -t iso9660 -t ro /dev/hdc /mnt/cdrom
Yes, /mnt/cdrom exists and /dev/cdrom -> hdc
(should that be /dev/cdrom -> /dev/hdc ?)
fstab:

At this point my balding head is balder and it's starting to ache...
a LOT!
TIA for any suggestions/ideas you can offer.
