I'm not really sure if that would work. I've run across MP3s in the same directory, all ripped from CD at the same time (years ago), in which some were ok and others weren't.
I did this dumb thing where I corrupted the file system, then tried to use fsch to recover it.
There's a famous series of list posts about ReiserFS:
"For a very good time, create a few dozen files containing images of ReiserFS filesystems on a ReiserFS (scratch) filesystem, and force an fsck.reiser. All of ReiserFS is a single B-tree, that can be anywhere on disk. So what fsck.reiser does is to search the entire disks for blocks that look vaguely like parts of the filesystem B-tree, and stitches them all together. Whee!!!!"
I have to stress, for anyone reading this, that Ubuntu didn't create my ReiserFS -- it was my own idea. Ubuntu uses ext3, which is much safer.
I had to do about four really stupid things in sequence in order to create my problem, none of which are likely to be repeated by a casual Ubuntu user.
