Thanks for the info What is the best percentage to use? I was thinking to split files with some type of parity record was to use QuickPar.. or RAR.. which is better.. (There's also dvddiseaster but it sometimes reads 'short' ie: a 4gb disc reads as 600mb.. some LBA problem.. For the RAR is proprietary.., what about Quickpar..? I have some bluray disc that I want to archive it to dvd till I get a bluray burner someday.. thats why I ask the question in the first place. but from my experience with bad dvd, I prefer to recover from the 'file' method than a disc method.. Most of the 'small' but unrecoverable errors are from when the DVD is switched speed from 2x to 4x, 4x to 8x or when switching layers at 50% There's lite on solidburn, WOPC, etc but thats for my next burner someday. Also 'verifying' data is too slow, and a scratch later will also make the read error anyway.
interesting reading but in my experience the recovery feature is rarely used by those who put rar files on internet
