I have an external 1TB USB drive that's also misbehaved since new.
It's my backup drive, and I've split into a 500 MB ext4 partition and
a 500 MB partition I use for Time Machine for my macbook.  It's been
extremely reliable with OSX, but I've had lots of problems with it on
Linux.  However, most of those issues were when I was running 2.6.32.
I run Debian testing, and as the kernels have cycled through 2.6.38,
2.6.39, and 3.0.0 it's become a lot more reliable.

Maybe the USB and ext4 drivers have gotten better at my particular
issue, or maybe I've just gotten lucky.  Anyway, I suppose it wouldn't
hurt to try a newer kernel if possible and see if that helps your
problem, too.
