Help! I backed up some large, important video files to a DVD a while back, but discovered today that some of them are now generating CRC errors. I'd like to copy the files to a writable medium (i.e., hard disk), so I can try to minimize the (audio/video) impact of the lost data, but my attempts to copy the files fail when they hit the first CRC error.
There are definitely some rather obvious scratches on the disc, which I had hoped polishing with commercial products would remove, but I still get CRC errors after trying that. I suppose I could grab the good blocks of each file off the DVD using "dd" commands, but that might prove to be a tedious task, and in any case, I'd rather rescue the (currently unreadable, but possibly still there) real data instead. Can anybody recommend: A) better disc repairing products, such as ones I've heard of that actually fill-in the scratches? B) software utilities that can copy (as much data as possible from) files that have CRC errors?
