Thanks! Ok, you've got SCSI CD-ROM support ... do you have SCSI generic support? "cat /proc/devices" should contain the line "21 sg" in the character devices section. The SCSI generic device files are /dev/sg0, /dev/sg1 ... but their existence doesn't mean much if you aren't running devfs (I guess you aren't based on what you quote in your post). cdrecord needs the generic device driver to send commands to the writer. This used to be more clearly documented in the manpage. -- Nathan Norman - Staff Engineer | A good plan today is better Micromuse Ltd. | than a perfect plan tomorrow. mailto:nnorman@micromuse.com | -- Patton
