If you use ide-scsi emulation, then you need to access the drive as a pseudo-scsi device, probably at /dev/scd0. (These device designators are sometimes distro-specific, though, so you should check if RH has changed thinng on you in the last version switch.) .
I notice that in all the tests you report doing, you don't report trying this one:
mount /dev/cdrom
which should cause the fstab entry you list below to be used to find the right device. I don't know if that will work either, but if the installation really did work correctly, then /mnt/cdrom should be a symlink to the correct block device (easy to check).
cdroast uses the device's (pseudo-)LUN to access it (something like dev=0,0,0), not its /dev/* entry, and I assume X-cd-roast is just an X wrapper for this app, so it does not help you find the correct /dev/* entry
As to the error messages you report:
"mount: special device /dev/scsi0 does not exist" means what it says -- the /dev/directory does not contains a device entry for /dev/scsi0 . Check with "ls -l /dev/scsi*" or something similar.
'unknown device' means that the device entry exists in /dev, but it does not point to an actual, physical device on the system. Try mounting /dev/scd0 instead.
Finally, on my system, scsi-ide emulation requires 4 modules, not the 2 you mentioned:
ide-scsi 7360 0
sg 23588 0
sr_mod 12760 0
scsi_mod 79480 3 [ide-scsi sg sr_mod]

I'm having trouble reading my CD-ROM (actually a LG(Goldstar) 8080 cd-writer) drive.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?)" [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?
