Is there a way to "checksum" a DVD already burned?


I know that k3b does this automatically if you ask it. However, right now I only have a crappy copy of some free utilities for Windows to burn CDs and DVDs. The stupid utilities ran at about twice the burn speed tolerated by the disk, although preliminary tests show that it turned out alright. I've had lesser speed increases utterly kill DVDs, though, so I'd like to do a checksum of the disk if I can.

I have access to both md5 and sha1 sums for the disk. I also have Windows, and Knoppix to play with for checking. Thanks for any help!

Okay, I'd still like to know if there is a way to check the burned disk for accuracy, but I found a creative way around my real problem. I just used Knoppix (actually Xenoppix) to burn a new DVD, since it can access my original DVD ISO still. It worked perfectly. Like I said though, I'd still like to know if my other DVD is valid.

You can do this but I don't know if it's an accurate md5sum.
dd if=/dev/DVD of=/dev/null|md5sum
