I have two hard drives, one that came with my 360 and another 120gb one we bought for more room. When I first tried to configure the extra one, I accidentally configured the old one, deleting everything. But that was a while ago, and everything is solved now.
However, the xbox only recognises the hard drives as memory units now. Again, no problem but Battlefield 4 requires a hard drive to play. So my question is: how do I get my xbox to recognise the hard drives again?
