    Hi all, something weird happened to my cd-rw after upgrade.
    I upgraded to testing and installed the kernel-image-2.3.24-1-k6.
    I logged on, ran startx and then ran xcdroast. Everything seemed to be working.
    I put in a 650MB cd-r disk into my cd-rw drive and began to make a backup of some files.
    at about 98% I got a write error. hmm.. that seemed strange. I mounted the cd-r in my cd-rom drive
    but got an error saying no compatible filesystem. So, I popped the cd-r into my Windows PC and
    the disk seems fine. all of my files are there. So back over to debian I popped in another cd-r disk
    and... xcdroast says I have no cd-rw drive. It also can not detect my cd-rom drive. I did not reboot
    or anything before popping in the second cd-r disk. very strange. So I ran modconf thinking that
    the ide-scsi driver wasn't loaded anymore. The ide-scsi module was in fact loaded sSo I removed it
    and added it back. Then I added an append statement to my lilo.conf

    here is the image entry in my lilo.conf:


        append="hdc=scsi hdd=scsi"
    # restricted
    # alias=1

    I looked in /etc/modules.conf and there is no entry for ide-scsi.

    With the system the way it is right now I am able to mount both the cd-rom and the cd-rw from
    /dev/scd0 and /dev/scd1 respectively but I can not get xcdroast to detect the drives.

    cdrecord -scanbus gives me the following information:

    #begin cdrecord -scanbus

    #end cdrecord -scanbus

    I also tried addiing this line to modules.conf but it seemed to have had no affect at all:

    options ide-cd ignore='hdc hdd'

    I even tried starting xcdroast with the -a option and also the -f option.

    I'm not sure what else to try. Strange that burning a cd worked that very first time.
    Does anyone have any ideas of what I should try next?
