That's correct. In other words, just using it as a CD-ROM drive. (I can write OK when I need to with X-cd-roast). > > It's not a hardware problem, and it worked in previous RH versions.

OK, done that - "mount: dev/scd0: unknown device" (there is a /dev/scd0 file, I looked, 11 bytes long) > 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' Hmm, /dev/cdrom is actually a link -> /dev/hdb OK, done that, now /dev/cdrom -> /dev/scd0 But mount /dev/cdrom /mnt/cdrom gives 'unknown device' again... > > 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)? Yes, that's what I want to do. > 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 ;) Well, the writing is (I expect) quite OK with X-cd-roast, and it will also read CD-ROM images quite happily. No problem there. But what I want to do, and can't do, is read files off the CD-ROM in the usual way as if it's just another filing system. Mount it, do a ls, copy a file.... Can't do it from the command line, can't do with Nautilus or the KDE file manager.... cr - To unsubscribe from this list: send the line "unsubscribe linux-newbie" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.linux-learn.org/faqs
