I have a Huges Directv HDVR2 that has never been modified in any way and is out of warranty. Apparently the hard drive has failed. The drive is a 3.5 Series Maxtor Fireball 3 ATA / 133 HDD 40 GB. I would like to purchase a replacement drive to get this unit working again. I'm not really interested in more capacity or hacking the system in any way. If I can get additional space simply by default of replacing the drive, that's fine by me. Can someone put me on the correct path to doing this as inexpensively as possible? I appreciate your assistance. Thank you.
