Viz. [root@RSivernell rick]# ll /dev/sc* | more brw-rw-r-- 1 rick disk 11, 0 Oct 11 13:07 /dev/scd0 brw-rw-r-- 1 root disk 11, 1 Oct 11 13:07 /dev/scd1 brw------- 1 rick root 11, 0 Oct 11 13:07 /dev/sr0 brw------- 1 rick disk 11, 1 Oct 11 13:07 /dev/sr1 note the major / minor numbers? They are identical. First. modern distros deprecate the use of srX, get rid of them, literally. Promise from me that you can do no harm by deleting them. 2) you don't appear to have /dev/scd2. Do a mknod 3) ln -s /dev/srX /dev/scdX iterate X 0, 1 and 2 ---- Each of your cd roms (all THREE) will iterate scd0, scd1 and finally scd2. Which is what is *impossible* to say as it depends on the order of module load, AND, which gets mounted first. (Blame the crappy scsi framework on Linux for that one, it's a brothel) As a fair and reasonable guess, your system (regardless of what you think you have in /etc/fstab) is as follows scd0 = hdc (because of append statement) scd1 = writer (lun #4) scd2 = reader (lun #5) > /dev/cdrom /mnt/cdrom iso9660 ro,user,noauto,exec 0 0 > /dev/cdwriter /mnt/sr0 iso9660 ro,user,noauto,exec 0 0 > /dev/cdrom2 /mnt/scd1 is09660 ro,user,noauto,exec 0 0 so that YOU don't get confused, scrap out all references to srX in both the fstab, and, obviously, the /mnt folder, replace them with the direct scdX name. again, scrap all symlinks to mysterious items like cdrom etc and use direct /dev/scdX's. By all means, change back after it's settled down, but first work in the literal world (kde makes special use of the name 'cdrom' incidentally) *Temporarily* disable automounters Finally, reboot, place a cd in each drive and mount each scdX to find out who is what. There *will be* a timing race between the hdc and the other devices. If it is mounted FIRST, it will *probably* affect the scdX order because it's device minor node doesn't get registered until the cdrom.o module is loaded. Thus, I don't want to complicate things here, but *if* it's mounted first it will be scd0, *if* not, it might be scd2. You are going to have to play.
