    cdrecord problems

    I am having troubles writing CD's. I have three different HP writers, all of which I know work (or I should say, the hw is not the issue) Tried different cd's, brands, types, etc. I have searched high and low on the internet, seen many of the same posts, but no resolution. Anybody have any ideas, fixes?

    Rehat 8.0
    2.4.18 kernel
    cdrecord 1.10-14
    IDE writers (all the correct modules loaded)

    Could you check for kernel message (/var/log/messages by default) that are posted at the time of the incidents?

    you are trying to write cd's as a normal user with a non-setuid binary. That means nothing to newer people. Try running it as root, see if that fixes it. If so come back, I will give you some more insight as to what/why it is happening.
    I respectfully decline the invitation to join your delusion.

    If you look at his prompt, you'll see that he was root.

    I was root, believe me. The "garett" you see is the current workng directory I was in. I have tried this on three different boxes too, different writers, different media, etc. Two Redhat 8.0's and one Slackware 8.0, same kernel rev's. This sounds like a bug somewhere. By the way, if I look at the messages file, it reports SCSI timeouts. Knowing that these IDE drives are emulating SCSI devices, this is expected. Exactly why this is happening, I am not sure yet. I also have a SCSI Travan tape drive that works without a hitch, but that is a bit different.

    This seems kind of strange, especially since you've tried it on the different systems. On my system it has always worked as soon as I've configured ide-scsi. Although I don't really believe that this is a kernel bug, could you try upgrading to the latest 2.4 series from

    Yes it is strange. If memory serves me correct, I though Redhat 7.3 worked at one time. I do not recall what kernel rev. it was....whatever came std. with 7.3. I suppose I could try updating the kernel. I have been sucessful writing CD's in the past. I just walked over to my buddies PC with RH 8.0, same error, same kernel.

    what distro and kernel are you running?

    Just to make things a bit clearer. Here is my approach.

    User = root

    # mkisofs -R -o crap.iso /home/garett

    # cdrecord -v -multi dev=1,1,0 speed=4 or 2 crap.iso

    Exactly what are the kernel message that you get?
