    Cd-rom missing

    Hey guys I just installed slackware 10 with dropline gnome so far everything works fine. except I have no cdrom, I looked in /dev and it wasnt there neiter was hdc ??? ??? here is my /etc/fstab

    Code:
    /dev/hda5        swap             swap        defaults         0   0
    /dev/hda6        /                reiserfs    defaults         1   1
    /dev/cdrom       /mnt/cdrom       iso9660     noauto,owner,ro  0   0
    /dev/fd0         /mnt/floppy      auto        noauto,owner     0   0
    devpts           /dev/pts         devpts      gid=5,mode=620   0   0
    proc             /proc            proc        defaults         0   0
    /dev/sda1        /mnt/USB    auto     noauto,user,rw,exec  0 0
    and this is all I get in dmesg

    Code:
    scsi3 (0:0): rejecting I/O to dead device
    FAT: Directory bread(block 65) failed
    scsi3 (0:0): rejecting I/O to dead device
    FAT: Directory bread(block 66) failed
    scsi3 (0:0): rejecting I/O to dead device
    FAT: Directory bread(block 67) failed
    scsi3 (0:0): rejecting I/O to dead device
    FAT: Directory bread(block 68) failed
    scsi3 (0:0): rejecting I/O to dead device
    FAT: Directory bread(block 69) failed
    scsi3 (0:0): rejecting I/O to dead device
    FAT: Directory bread(block 70) failed
    *goes up to block 94 ???*
    EDIT: Also I have hdc=ide-scsi in lilo and i'm using the stock 2.6.7 kernel
    TIA

    Re:Cd-rom missing

    Check which modules you have loaded. Using ide-scsi you'll need srmod loaded, and the device you use will be /dev/sr0

    Also of note is that in 2.6 kernels, you don't need scsi emulation to burn CDs. You'll have to figure out how cdrtools works when not in scsi emulation mode (I haven't yet), but that could help. Alternatively, once you do figure out what your device is (I've seen them pop up as /dev/scd0 when using scsi emu), you can symlink to it with a "ln -s /dev/scd0 /dev/cdrom" and that should let most programs know where your cd is.

    without scsi emu you can do cdrecord dev=/dev/hdc speed=48 -eject -data foo.iso or whatever. I say disable scsi emu.
