Eeee, anybody? I too have run into this problem too. First i did a simple copy and paste and most of the games on my new hard drive and tried but most of my games wouldnt load. Plus i noticed sometimes my 360 hangs forever on the xbox splash screen now with the new HD. Decided to to use Acronis and did a 1 to 1 mirror image of my old hard drive and I confirmed all files did get transferred to my new larger hard drive.
But still have the same problem. My xbox can read the HD through file manager and I have renewd my game path as well but still nothing????????
Reformatted 3 times and made sure its a Fat32. Anyone else besides me and samadk00 have a solution? Sorry to highjack samadk00 btw.
