So, as soon as I got my new VIP 722, I enabled the external hard drive feature, and connected a Maxtor 750 gig (and, btw, I would not recommend that hd at all because it has a very annoying flashing light). It worked fine for a few days, and then it started doing strange stuff. For a while, I could view programs stored on the disk without problems but it gave me an error statement everytime I tried to transfer. The fix was always disconnecting the USB cable, and then reconnecting. Each time I did that, the problem cleared up completely. After doing that, I'd sometimes have to reboot to get it to recognize the HD. The other issue I have is while viewing programs stored on the maxtor external drive. A few times, I hit the pause button, got up and did something, and then came back and hit play. Each time, it ignored the presses of "play" and would not drop out of pause. The work around is to hit the skip back botton which puts it in play mode again. Anybody got any clues as to what all this about? I'm going to try swaping out the USB cable tonight because I wondered if a lose connection of some kind is at fault.
