My HD XL has rebooted several times while recording shows this past week...which pretty much means a hard drive problem, right? I've tried the boot codes 57 and then 54 and let the tests run, but it doesn't find anything, so...should I pull the drive and run Spinright on it? I'm hoping it's not TOO hard to open this up and get the drive out to test it? I guess if I need to buy a new drive, Weaknees.com is a good/safe resource? Any catch to replacing the drive, like that you can only do it once or something? If there is a problem, at least it's happening during the summer... I soooooo wish Tivos had built in RAID 1 and easily swapable drives! I'm more worried about my Tivo's drive failing then my PC's drive!
