Just curious, but is there any reason why you couldn't create the CD image on a bulk sequential medium, like a tape? I believe that the mkisofs program doesn't do random I/O, just sequential, so this ought to work, right? You might have to burn the CD in "slow" mode given the transfer rate of the DAT drive. louie > Note that burning a CD is a disk-space-intensive, two-step process: > (1) you create an CDROM image file from the files that you want to go > onto the CD, and (2) you burn the CD using the image file (and NOT the > original directory tree).
