Recently my 360 requested an update. I agreed to let it update, but a message popped up saying I had no memory to allow the update. When I restarted the console and did NOT agree to receive said update, the xbox seemed to have wiped all of the memory. I tried going to the "Storage" setting but nothing shows - it says I have zero memory, not even the internal drive! I also cannot redownload my profile because it says I don't have the memory capacity to do so. It seems to me that the HDD is corrupted or no longer readable. What do I do?
