We're excited to announce that we've fully migrated the Xbox Forums to their new home, here on the Microsoft Community forums!
As of today, going to forums.xbox.com will redirect you here to the Xbox area of the Community forums. We've moved all of your existing threads over so you can continue and start conversations with the new forums experience.
We sincerely appreciate the feedback you have provided over this transition and can't wait for you to check out the new Xbox Forums!
Unfortunately, unless you backed up your stuff somewhere, you have lost most of your stuff. Where did you buy that Harddrive? It worries me that you said preowned, because someone could have done something to it, especially if you bought it on Ebay.
