I'm about to move a lot (like 100) of old backups made on DVDs to my new NAS. The procedure I will use is simply: put a DVD in my Windows 7 PC, move its content to the NAS, repeat with next DVD.
If Windows completes the copy without complain about CRC errors or any other error, can I be sure that the copied files are identical to those in the DVD?
Due to the quantity of files I can't check them one by one, in case windows not complaining is not enough, what would be the best way to do it?
EDIT: I ended up using this free tool to automate the calculation of the checksum of the files in the DVDs
