My really old Hughes GCEBOT started freezing a lot - not just during live play, but also during recorded playback and traversing the menus. It's been really hot, so I thought it might be overheating. But, no, it reported normal. I did a reboot with no change. So, I finally decided it was time to do a total system reset (or whatever it's called when the whole box is erased). Well, it seems to have solved the problem. I get no freezes at all now. So, the question is, what did the reset actually do? Does it reformat or scan the disk and lock out bad sectors? Does it defrag the disk? I have a feeling that I was running into bad sectors on the disk which I will eventually encounter again as the drive fills up. Oh, BTW, I have two drives in the box. If one is failing, is there a way to tell which it is?
