Hmph, maybe I can shed some light. With my experience of an E68, it's basically never been a permanent thing, usually it means an insufficient powersupply, but if you get a message telling you something about the Harddrive, this is most likely a very rare occurance that has to do with a conflict in information relaying from your Xbox Micros, to your HDD boot sequence. Common cures can be, "1: Search for damaged save-game files" "2: While the Xbox is powered on "W/OUT" the HDD, connect the HDD." This will automatically reboot your Xbox. If that doesn't work, "While you have the E68 error, try removing the HDD, this will also reboot your box.. I assure you, no damage will come from this..

If you are able to boot the xbox with the HDD atached, go into your system blade, access Memory, highlite HardDrive, and press (Y) for device options, from this screen press the following sequence, [X, X] [LB,RB] [X,X]. This will bring up a blade asking you if you wish to reformat the HDD, do so.

This is commonly known as the Cache dump, but it does much more than that. Aside from removing localized information, it is known to remove all your updates, besides the Concole dashboard one.. but this is a good thing, because sometimes Title updates have been known to conflict, causing this issue..

It's rare indeed, but I hope this helps.. if not, try removing the plastic covering that your HDD sits on when connected, "reccomend doing this on it's side."

Ok, I know this is late, but I fixed the problem.

Much like the RROD fix, with raising the motherboard to the cooling units, and cleaning up the old coolant compound with new compound, the trick it, to make sure there is nothing on the little prongs next to theGPU. You'll see em. Basically, I got it to work solid for a few days, then it did it again...

sadly, the stuff I used was Arctic Silver 5, it's the best thing you can get, easy to find at RadioShack.. but the problem is I can't get it to solidify easily..

So if you don't mind a little abuse on your box, just cook it in a towel, I prefer using Nylon blankets.. they don't transfer lint into the fans likepillows or towels..

make sure the power corde and the A/V cable are hooked up to it.. just let it boot, and overheat until it shuts off and shows 2 red light.. if it shuts off and does not show the 2 red lights, it's really no big deal.. While it's hot, you have 2 choices, try to shock-cool the motherboard by placing it in the kitchen for 5 minutes.. that was it cools down in a clear environment.. or while it's hot, put your harddrive back on and reboot the thing.. Mine works after I do this, sadly that's all I can say, at least you can get it working again... but it's no permanent fix..
