If I *really* *needed* to get these files, I'd probably try something like

The reason I've been copying these dvds back onto my harddrive, is because I
recently set up a raid-5 on my system to act as my media server.

I've completed recovery now and have ended up with maybe a few gigs of files
(out of hundreds of DVD's) that can't be covered. I think that's a pretty
good recovery rate... and the files that were lost aren't exactly rare, so I
should be able to find them again.
