Hi! I was experiencing problems restoring recordings > 300GB from my external HD to the EMPTY internal 500GB HD. I would get a message saying there wasn't enough space. After deleting all recordings on the internal HD, I noticed I apparently had available space for only 55 hours of HD recordings or 330GB of SD recordings. That first number seemed too small, so I thought I should reformat the drive to clear up some apparent errors. I had found some secret commands to do so, so I attempted to format the drive. All seemed fine. The interface said it was 'cleaning' the drive, and that my unit would restart after it had done so. After a few minutes, the unit rebooted itself and a few minutes later, instead of displaying the usual interface, the front panel red (recording) lights would start blinking, alternating. I thought: Oh, I damaged the drive! I decided to test my theory by disconnecting the SATA cables from the drive, to no avail. The unit would not complete its boot cycle. The red lights blink non stop. I tried disconnecting the unit from the power supply, and plugging it back in, to no avail. The symptom continues. It's not the HD. By the way, it's out of warranty, and I own it, so DISH may not come to the rescue. Any help will be greatly appreciated.
