file system check software



Guys,

As I move through this corrupted file system problem, I'm going to have 
to wipe out my 7 terabyte file system and rebuild it. But not that I 
live in a world of data paranoia, I'd like to run some kind of file 
system checking software. Does something like that exist? Basically I 
need to write large (multi gigabyte files) filled with random numbers 
and copy them around and do diffs and md5sum checks. This should go on 
for about a week of continuous write, read and checking.

I could probably put a shell script together to do this, but it would be 
great if there were something 'out there' that did the job for me....

Cheers. Steve.
