You are having trouble reading CD-ROM discs in your CD-RW drive, am I right?
It's not a hardware problem, and it worked in previous RH versions. (It also installed my current RH 7.2 system quite happily).
My /etc/fstab reads /dev/cdrom /mnt/cdrom iso9660 noauto,owner,kudzu,ro 0 0
But, even su root, trying to mount it with (from memory):
mount /dev/hdb /mnt/cdrom gave (from memory) 'unknown block device'.
Trying X-cd-roast told me that ide-scsi was missing.
Trying insmod sg told me that sg was already installed, and 'insmod ide-scsi' successfully loaded ide-scsi, after which X-cd-roast now reads a CD OK (and presumably, would write).
However, I *still* can't mount or read a CD-rom in the normal way, from the command line.
This is what happens:
[root@localhost /]# mount -t iso9660 /dev/hdb /mnt/cdrom
"mount: bad fs type, bad option, bad superblock on /dev/hdb, 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?)"
You can't mount your CD-RW as hdb since it's now being emulated as a SCSI device. Try
mounting it with `mount /dev/scd0 /mnt/cdrom' and see if that works (assuming this is
done with ide-scsi et al currently loaded). You might also want to change the symlink `cdrom' in /dev to point to `scd0', something like (as root): `cd /dev ; rm cdrom ; ln -sf scd0 cdrom'
The only questions that remain to be answered are:
(1) Do you want to use your CD-RW drive *only* for reading CD-ROM media (which I doubt is the case here), or
(2) Do you want to use it to read and write CD-ROM/CD-R(W) media (which is a more practical use)?
For the latter, you will have to tell the IDE CD-ROM driver to ignore hdb all together, and assign ide-scsi to hdb at boot. More specific details can be gleaned from the CD-Writing HOWTO ;)
[root@localhost /]# mount -t iso9660 /dev/scsi0 /mnt/cdrom
"mount: special device /dev/scsi0 does not exist"
- and the same result for sda, sr0, and so when I try it, except that /dev/sda gives 'unknown device' instead.
If I try this:
[root@localhost /]# mount /dev/hdb /mnt/cdrom
I get:
"dev/hdb: success
mount: you must specify the filesystem type"
But when I cd into /mnt/cdrom, there are still no files visible...
So it doesn't want to know me, either as a IDE or a SCSI drive. dmesg shows it correctly:
"hdb: LG CD-RW CED-8080B, ATAPI CD/DVD-ROM drive
............
Type: CD-ROM ANSI SCSI Revision: 02"
I've tried reading the CDROM HOWTO, but I can't see anything there that explains the problem. Does anyone have any suggestions what to try next?
