CD-RW CDROM and you!

For some reason I cannot access either my CD-R or my CDrom in linux. From root or from user.

IDE1 Primary = 6GB WD - Windows OS
IDE1 Secondary = 80GB - 1g swap - 8g Linux OS - rest VFAT
IDE2 Primary = CDRW
IDE2 Secondary = CDROM

All the information I could think of that may help.

What error message are you getting?

Maybe ide-scsi is the problem.

Latest versions of cdrecord don't need scsi emulation, so it can detect your CD-R device using cdrecord -dev=ATAPI: -scanbus.

Try disabling ide-scsi and configure your CD-R in fstab as a normal CDROM device.

Check symbolic link /dev/cdrom too. Maybe it's pointing to /dev/hdc. If it does, your CDROM is not configured in fstab.

i'd also take a look at dmesg and see whether they're being recognized at boot - let us know

mount /dev/scd0 /mnt/cdrom should work...
