Even at 8, you're talking about moving your data to 12 DVDs. That means splitting your data into appropriately sized chunks. In the time you'll spend doing this, you could have paid for a new hard drive and then some. > When I try to mount the optical drive using 'mount /mnt/cdrom' bash tells > me 'mount: /dev/sr0: can't read superblock'. > Mounting is only valid for existing filesystems. > > A web search for 'linux copy files to new dvd' finds many hits on how to > copy files _from_ a DVD as well as a plethora of hits on using cp.

The trouble is that it doesn't do the legwork for you, which includes steps like setting up the filesystem of the optical disc. Some of the graphical tools do this for you. I don't know if any of these are available for Slackware. Ubuntu comes with a tool named "CD/DVD Creator" or similar. Look at the info for mkisofs. Once you create an ISO image containing your files, you can then burn that to the DVD, which will then allow you to mount and browse those files in the same way as if you had used cp or mv. -wes _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
