Problems with IDE CD burners and loading/unloading ide_scsi module - Linux Setup, Configuration & Administration

Hi folks, Well, I'm sure this must be doented somewhere, but I can't seem to find it on google. The problem is simple. I've got an IDE cd burner, so I need to use the ide_scsi modules. 1) They don't seem to get loaded properly so I have to load them manually before burning 2) They don't unload when I need to do things like mount a cdrom w/ filesystem or play and audio cd.

    Default Problems with IDE CD burners and loading/unloading ide_scsi module

    Hi folks,

    Well, I'm sure this must be doented somewhere, but I can't seem to
    find it on google. The problem is simple. I've got an IDE cd burner,
    so I need to use the ide_scsi modules.

    1) They don't seem to get loaded properly so I have to load them
    manually before burning
    2) They don't unload when I need to do things like mount a cdrom w/
    filesystem or play and audio cd. So I have to unload them and reload
    the regular ide-cdrom modules.

    Is there a way to solve this? The users in my lab will have a really
    hard time burning CDs and such with this problem ... as they of course
    don't have root access.

    Thanks all,

    Dave Topper

    What distribution are you using?

    Why not just use the ide-scsi driver all the time, then access the device
    at /dev/scd0? As for allowing non-root users to mount data CDs, play
    audio CDs, or burn CDs, that varies slightly per distribution. Ditto for
    making sure ide-scsi gets loaded when needed.

    The ide-scsi emulation mode is not needed any more. Take a new kernel and a
    new version of cdrecord, mkisofs and cdrdao. Kick ide-scsi and get
    dma-support instead.

    Hi,
    I am using an IDE CD-ROM burner under Debian.
    The modules I use are the sg and ide_scsi modules.
    You can auto load them by placing the module names in /etc/modules
    In /dev, my cdrom is a symlink to the scd0 device, so I never need to
    use the cdrom as an IDE device.

    I also have used append="hdx=ide-scsi" (replace hdx with the proper ide
    device: probably hdb, hdc, or hdd)

    also you remove a module stack with modprobe -r module
    and sometimes modprobe -q iwll load stubborn modules.
    check the manpage :-)
    I hope this is a little helpful.
