My HR-44 decided to reboot itself this morning upon turning it on. It started scanning the hard drive for errors and found 30 some errors but then it got within one error of correcting them all, it found 30 some more errors. This cycle won't stop. I turned the receiver off after it was over 1200 errors. Is my hard drive failing? Any suggestions to fix this? Do I need to call DirecTV and get a new receiver? Thank you in advance for your help.
