Most likely, a DVD connected via a USB port will show up as a SCSI device, with a name like /dev/sda or /dev/sdb. However, to burn a CD/DVD, you don't mount it (there is no file system to mount on a blank disk).
Generally, if you power up the USB drive first, then boot the PC, k3b will find and recognize the drive. Also, as root, you can execute "cdrecord --scanbus" to find the "SCSI" drive number for your CD drive. Mark and/or Crawford may want to correct me here, or expand on the explanation, because my understanding of how USB is mapped to SCSI, and how CD/DVD-ROM drives are handled on Linunx is shallow. -- Bhaskar On Mon, 2005-03-21 at 18:01 -0800, Kevin Toppenberg wrote: > Bhaskar, > > Thanks for your advice here.
