It froze up on me, which isn't uncommon. But when i went to reset the receiver, it started counting up hard drive errors. It was up to 137 errors and counting, with 4 fixed, and i was still only on 1% complete. It said it could take up to hrs to finish, and i just lost it. Of course, i have many other things going on in my life that helped contribute...it wasn't the receiver alone. But the dtv receiver, unfortunately, is what set me off.
