Another thing I can suggest, when dealing with things like Linux ISO
images (and other things which are freely available via rsync) is to use
readcd (or even dd) to read as much as you can from the CD (usually only
the last few sectors give errors) and then use rsync against one of the
public mirrors to "fix" the image - which will only take a few minutes,
and will use negligible bandwidth.
