But trying to play the Music CD from the CD-RW, DVD and Standard CD-ROM drive didn't work. They all worked fine before. The Music CD plays in my stereo. I can't access any CDs. Trying to access the CD drive gives me: Could not mount device. The reported error was: mount: wrong fs type, bad option, bad superblock on /dev/cdrom, or too many mounted filesystems. I had to give my cdrom scsi emulation for it to write. I also added lines in rc.local to insmod ide-scsi and lines in modules.conf that I got from reading MP3 writing to CD HOWTO. I can still write to the CD-RW but not mount it. I did use some commands that I wasn't certain about as well. My /dev/cdrom should now be /dev/scd0 which I've changed in the /etc/fstab. I am going to try and get all CD-ROMs working again by reversing everything I did then try and get my CD-RW working both reading and writing. Just to keep you uptodate my next mission after getting this completed is to test my DVD ROM out. So expect me back here after I've fixed the above problem also I might try my scanner as well.

It will be a good idea to print out /etc/fstab from time to time. You will see changes (I hate the system making changes without asking me). You should be able to mount a CD with 'mount -t iso9660 -o ro /dev/xxxy /mountpoint'. The xxxy will depend on what the device is called today, mountpoint would be /mnt/cdrom if you use the standard one (I make and use /cdrom). The 'mount /mountpoint' command uses what is in /etc/fstab. If that is 'wrong' you get errors. Mounting from KDE or Gnome will do the same. All great fun, isn't it?	Guest (0)

I won't put it all down as it's long. Attached scsi CD-ROM sr0 at scsi0, channel 0, id 0, lun 0 sr0: scsi3-mmc drive: 40x/40x writer cd/rw xa/form2 cdda tray I/O error: dev 0b:00, sector 64 isofs_read_super: bread failed, dev=0b:00, iso_blknum=16, block=16. It repeats that error for a couple of times then moves onto the next drive with a similer error except block=32 for the next two devices (DVD and Standard) Another line is hdc: command error: status=0x51 { DriveReady SeekComplete Error } I tried mounting my CDROM drives but they report the same error I get in KDE. I also looked at the modules I've got and I am uncertain which ones I need. I know the ones I added but the rest I am uncertain about. Here's what I get when running lsmod these are what I added following MP3 writing to CD HOWTO. sr_mod, sd_mod, ide-scsi the ones I added were imm, parport_pc and ntfs. I lot of modules though that I have no idea about are bsd_comp, slhc, nls_cp437, binfmt_misc, nls_iso8859-1, jbd. I don't remember adding scsi_mod but it could have been there before. I am uncertain. Guess it's a good idea to print out everything about your computer. Well I am not afraid to reformat and reinstall Red Hat when everything goes wrong. I keep backups of all the files I installed. I may do that and this time print out an inventory of everything.	Guest (0)
38969	2002-03-13 14:35:00	OK everything back to normal working fine. I reinstalled Red Hat and I'm not sure if I did anything different but I can write CDs because the ide-scsi module was loaded this time. I am confused as to what just happen but reinstalling it just solved my problems. I can access my CDROM drives no problems at all. Now off to read on getting my DVD to read if it's not already doing so.	Guest (0)
