    Have you test it with cdwrite -y ? I think this is a cheaper hardwaretest. :)

    I am using an Asus-SC200 NCR-Hostadapter. My Hardisk is SCSI on the
    same adapter and the CD-Rom, too.

    If there is only _one_ session on your masterdisk, try this:

    --------------------------------
    [root] ~: more burnhot
    #! /bin/sh -

    CDROM="/dev/scd0"

    size=$(isosize $CDROM)

    if (test $size = 2162688) then
    echo Keine Master-CD im Laufwerk!
    exit
    fi

    echo "CD-Groesse:" $size Bytes

    cat $CDROM | buffer -p 75 -m 10M | cdwrite -v -b $size -s 2 - &
    renice -20 buffer
    renice -20 cdwrite
    -----------------------------

    The writer is a HP4020i (CD2000) and the cdrom is a Toshiba 3601
    quadspeed.

    I have done more then ten cdr by this script without a problem. I can
    use the computer very hard when I am burning. It works like a dream!!


    BTW: This works only if there is one session on a the mastercdr. If
    there are more sessions than you got only the first one. Perhaps a
    kernelproblem? I can't understand why cat /dev/scd0 not give the full
    cdr.


    And now a look inside of my computer when I cut a CDR. (486DX133)

    Cut a CDR by Windows? ROTFL!
