Lost a partition and recovered some it. Not all of the video files are working. Is there a tool that can scan your whole hard drive/folder for video files that have errors or are corrupt? Thank you.

How did you lose a whole partition? Usually it happens when the partition table gets damaged;
the files and index structures on the disk are usually intact. if they're not intact recovery likely to better on NTFS
Vs. Fat32. I don't think you're going to find any tool like you're describing.

I was resizing and moving the partition. It was running for awhile and I wasn't paying attention and hit the reset switch. Got back in Windows no partitions showed up. Made a new partition without thinking. Bad day for me, wasn't thinking that day lol. Was able to recover most of it. Some of the movies I recovered have errors in them. This is one of the errors from VLC

No suitable decoder module: VLC does not support the audio or video format "undf". Unfortunately there is no way for you to fix this.

Sorry to hear that - bit of a nightmare scenario.
If I were you, I'd look at them with a hex editor. You'll tell pretty quickly whether it's valid data.
It might be just junk. For example, with AVI, if you look at a known good file of the same type, you'll see a page or two of header info,
followed by the video / audio interleave (looks like random letters and numbers) and the index at the end.

Virtualdub has a hex editor/viewer under the tools section.
