    Hi All,

    just to delve into this a little more; what are the default udev
    permissions/ownership for /dev/hdc /dev/scd0.? I get the following,

    [root@localhost dev]# ls -alh hdc scd0
    brw------- 1 coolboarderguy disk 22, 0 Mar 9 2005 hdc
    brw------- 1 coolboarderguy disk 11, 0 Mar 9 2005 scd0

    Shouldn't they be owned by root..? If no, then I get problems with
    cdrecorder/K3b. Burning stops mid-burn and gives the 254 error saying
    that cdrecorder is not with root priviliges. Little confused. Cheers.

    Mark Sargent.
