I should have titled this uses or fixes, sorry for that mistake. I have two 360 HDD's both 250GB. One when I plug it in just has A bunch of corrupted files. When it corrupted I tried to format it and it didn't work. The second one is brand new, I gave my brother A Call of Duty: Modern Warfare 2 Xbox 360 for Christmas. I think he tried to update it and it wouldn't work. I can't remember what happened with his. Coincidentally mine was from A Modern Warfare 2: 360 as well. I have A transfer cable, my laptop won't seem to recognize it or my HDD's. I'd like to find some way of getting them to work again, even if I can't use them for my 360 I could hopefully use them as external drives for my Wii or laptop.
