It is SOOOO nice to have a box that says "6%" full (instead of 80%) when you have 6 hours of HD programs recorded!
So far now several days after the reformat hard drive procedure my DVR is still doing OK and no longer filling up insanely fast. 45 hours of HD content, plus 5 and a half hours of SD content, is taking up 50% it says. Reasonably sure the hard drive is 500 gb, which from all I've found in my research means that, if anything, it's underreporting now. It might be that the percentage will increase more quickly after the halfway mark. We'll see if it continues to function like this or if it starts going insane again and filling up too fast and deleting my shows and all that nonsense.
If you ever want to knock out a couple of the percentage points you can try purging the cache at some point. I'm not sure exactly what causes the cache to get fuller but I am sure it slowly fills up over time and purging it can give you a little more room. This doesn't get rid of your programs or your settings, or at least it shouldn't. I just did it the other day.
On mine to purge the cache you just:
1. First look at how full the DVR is so you can compare the before to the after
2. Keeping the box on (it might work with it off for all I know but I haven't tried it that way), hold down OK/SELECT and be patient
3. When the little light (I think it's the on/off light) starts blinking, lift your thumb up and push and hold OK/SELECT again and be even more patient
4. When the little envelope signal finally appears, let go of the OK/SELECT button and press the LEFT button (the one just to the left of the OK/SELECT button)
5. Then it will tell you via scrolling instructions on the box that if you want to purge the cache, push the CHANNEL UP button (and it will also say I think if you want to change your mind and not purge the cache push the CHANNEL DOWN button), so push the CHANNEL UP button.
6. Look at the percentage full and see if it hasn't decreased a little.
