got a new hard drive today plugged it in to transfer some files all went well until i updated .
the HDD now won't boot and it gets to the microsoft logo and crashes and repeats to do that !
it boots fine if there isnt a HDD in the xbox
i've also tried this on another xbox 360 .... same issue .
on a multiude of forums i've visited people said the update can go wrong so hold the sync key and power the xbox up and it should remove the newest update and fix the problem .
it didn't so same problem :(
can i get some help please !!
