The typical answer is: "because it is always getting corrupted again".

This could mean you've managed to messing with an ext4 filesystem as if
it were ext3. That won't corrupt file data, but can cause lots of other
problems, and could cause data loss if you manage to confuse the kernel
and the fsck tools enough. With some luck, it will end up in lost+found
after the proper fsck.
I sure hope that's what is happening.

You should do a 24H memtest86 marathon on that box. And you should make
sure you're *always* using that filesystem as ext4, since you apparently
have a part of it using ext4 features.
If it is a hardware problem, it is a strange one... it should be messing
with the entire disk, not just a set of files in the same partition. It
can't be bad magnetic media, as that causes sector read errors, not
corruption.
I hope this answer helps you. I won't be able to help you further on this.
Maybe someone else can (or has a better idea of what the problem could be).
