Is anyone using rewritable dvd discs as data discs (not video) for
backing up their files? Someone in a newsgroup is saying that
rewritable discs are too unreliable for backups.

I tested one of the backup discs I recently mdade and using the
DVDinfo program it finds lots of errors. I'm now in the process of
copying the big 4.6 gig backup file that's on the dvd to my hard drive
and that's proceeding without any apparent errors. On the other hand
I can't see any way to get windows to tell me if it's getting soft
errors or doing retries, which could be happening. (Does anyone know
how to get windows to report retries and soft errors on a dvd drive?)
