This is from the CD-Writing-HOWTO, section 1.6 (paraphrased).
If this is a Linux CD, and you have long filenames, and you're not
using Joliet, then you're using Rockridge extensions. These are designed
to allow long paths, long filenames, and all the permission information
important on Unix but unknown to Windows. Unfortunately, Windows does
not understand Rockridge extensions. Which would explain why no usable
backup would be possible on a Windows system.
OTOH, I've never scratched up a CD bad enough to make it unusable. (Of
course, I try to keep sandpaper and CDs at least ten feet from each
other, kinda like keeping floppies and magnets ten feet from each other.
;-) And I imagine that if you did, there would be some generous SLUG
member who could burn a copy of the damaged CD for you.
