I recently upgraded my softmodded xbox hard drive, i followed one of the guides from here, it works fine except for the fact that it only half of the hard drive works the other half is not shown or is not useable. this is the guide i used: http://www.how2xbox.com/harddrive.htm
if your hard drive is larger than 137gb then you have to format a g partion. You can do this by installing UnleashX as a n App and then selectiing format g partion.
