I have an HR21-700 with an upgrade drive and if I record an MLB game via extra innings it will not let me view it. Instead it goes right to the delete screen and will only let me delete it. I called DirecTV who advised me it was a corruption on my hard drive. They talked me through the hard drive reformat (via the front buttons) but it did not seem to work. It reset everything alright but it should have wiped out even my settings and they were not wiped out. It looks more like a reset than a format. Besides, the record light only lit for about 5 seconds during what was supposed to be the "reformat".

Anyone know it there is some other way to reformat these units with upgrade drives?? DirecTV said if this didn't work I'd have to replace the unit due to what they said was probably "bad sectors" on the drive???
