Last year, my 250 GB hard drive had requested to install an update for the dashboard before I actually connected to Xbox Live. I downloaded it then I realized that my background and avatar. Then I checked my storage devices and it stated that my Xbox hard drive was unformatted. I reformatted it and installed everything back again and then last week (Today is October 24th 2013) It had done this again and I wasn't paying attention and downloaded a dashboard update again before connecting to Xbox live and I lost all my data again and it took me 4 days to reinstall everything. Today I had to install an update for Battlefield 3 (Which I bought about two months ago) and I received it while online. I installed this and it unformatted my hard drive AGAIN. I have never done anything that would possibly harm my hard drive and I cannot explain why this is happening. My guess is that the lousy employees at Gamestop sold me one that is broken on the inside somehow.
