Good evening. I am a 68 year old grand farther with a bunch of grandsons and three Xbox360's in the family. One of the boxes arrived without a hard drive and I need to get it working. The paly station is a Xbox360S and the hard drive I am trying to install is a 500GB Western Digital BPVT. I have formatted it to exFAT on my laptop but the play station does not recognised the drive. Any advice will be appreciated.
