I've lost Dish HDDs before, especially before there was the EHD option.
Sigh- the 721 was SO good. When it worked. I went thru 6 or 7. If it wasn't the HDD, it was the power supply.
Lost a couple of PPV recordings. And, of course, the one I was in the middle of was no longer available. Something about Masters and Johnson. Wasn't very good, anyway. But I paid for it.
