I bought a dvd which has more than 50 video files (flv format). How can I check in linux if all the files are ok and dvd is not having any errors, without playing each and every video?
One simple method I think works is simply copying all files to a temporary folder on hard disk. If there are any read errors they will show up. The hard disk files can later be deleted.
Can I use dd command for this (without copying or copying to null device) as follows?
If you had a checksum for the DVD -- such as an MD5 sum -- you could check that. It would check the actual data, not just that the blocks are readable as dd does.
@catkin: That is right but there was no checksum of the dvd available. Probably, it should be mandatory for companies selling CD/DVDs to provide checksum along with the cd/dvd, or at least on their website. Ideally, on every cd sold, there should be a simple application in root folder which would check the checksum on command.
