My ViP722 is going bad and I'm scrambling to save the recordings I have on it. I purchased a "WD My Passport Ultra Portable External USB 3.0 Hard Drive, 1TB" and I'm having some problems formatting it. Questions: 1) How long should an initial format take? Is this a five minute thing or something that should be done overnight. 2) Is this drive supported? I've seen that people have problems using the drive with Linux. Will the ViP722 accept it? It looks like a very popular drive. I'm asking because after I plug in the drive I go through two confirmation prompts about formatting it. Then the receiver starts a formatting screen and switches to a 2nd screen saying not to touch anything while the format is going on and the receiver reboots. After about three minutes the screen goes black and the receiver does nothing, the green LED also turns off on the receiver. I can't cold-boot the receiver until I unplug the USB from its front port. I don't know if this problem is because of a broken receiver or an incompatibility.
