A friend handed my a DVD supposedly having a backup of his kids photos and videos. The DVD shows as empty in Windows 7, but I can see that data was burned in the disk.

Is there a utility to explore all the disk and try to restore the data available?

I've searched but the most of the tools focus on scratched disk. Not the problem here.

It would really help to know what software he used to make the backup. The format may be proprietary and need special software to read. – Chris S Dec 18 '11 at 16:11
@ChrisS: ok, I'll find out (probably tomorrow because was copied in a PC shop, ironically) – Eduardo Molteni Dec 18 '11 at 16:18
what do you mean, you can "see" data was burned to the disc? – wizlog Dec 18 '11 at 16:21
@ChrisS: Aren't all files burned in a standard way so all drives can read them? – Eduardo Molteni Dec 18 '11 at 16:23

I'm sure that somewhere there is free software that would do this for you, however as of now, I can't find any.

DiskInternals CD & DVD Recovery offers a trial that allows you to test for files on your CD/DVD. You may need to purchase the program to receive full functionality.

(if it doesn't work, you can try Discgetor.)

Additionally, it may help if you installed the backup utility on the computer that shows a blank disc.

You didn't specify an operating system in your question, so I'll assume your using Windows. If you burned the disc on Windows 7, it might not be readable in versions of pre Windows XP. )
