I'm going to bet this drive is out of warranty.  I'm pretty sure it is
over 2 years since I bought it. 

Once I replace that drive, I'll dd the thing and see what it does then. 
It'll either break it or give me a fresh start to play with and see how
long it lasts.

I'm using lvm here.  I also don't have a mail server set up which is why
I run them manually.   I usually do it once a month or so but had some
family issues to pop up.

I figured the short test wouldn't say much.  I am backing up some of the
stuff tho.  I do have a 750GB drive that was empty.  It won't save it
all but it is a start.  Test should have been done by now but I guess
the copy process is slowing it down.  I'm getting this so far:

# 1  Extended offline    Self-test routine in progress 70%
