>Description:

When trying to test-burn and really-burn a DVD, I got the following
experience:

    [/home/ftp/pub] root at k7>burncd -t -f /dev/acd0 data dd.iso 
    next writeable LBA 0
    writing from file dd.iso size 7443022 KB
    written this track 7443022 KB (100%) total 7443022 KB

    [/home/ftp/pub] root at k7>burncd -f /dev/acd0 data dd.iso 
    next writeable LBA 3721520
    writing from file dd.iso size 7443022 KB

    Input/output error

So the test run (-t) started at LBA 0, but the real run started at
3721520. The disc doesn't get recognized by a DVD player after this
test, which makes me believe that the disk is written on during the
test burn.

The DVD burner is: <HL-DT-ST DVDRAM GSA-4167B/DL10>
