You might be better off, given what you describe, getting a new hard
drive and then restoring the data from backups.

"It broke." This "shouldn't" happen if you're using ext3; if the
system spontaneously crashed, the filesystem should be more-or-less okay.

When this happened on my laptop, I really strongly suspected bad
hardware. I eventually came to the conclusion that, sometimes, bit 2
on the IDE channel was getting set to zero, regardless of what it
should have been, and this was somewhat unsurprisingly nuking
important filesystem data. Given that you've had similar problems
with this hard drive before, I'd really strongly suspect hardware
issues.

Linux pretty much ignores the filesystem-type word in the partition
table. Also, ext3 *is* ext2, just with an added journal file. So
this isn't really indicative of anything; you'd get the same results
on a healthy system.
