you won't know till you try it but DON'T HACK WITH THE ORIGINAL DRIVE, if anything goes wrong you can always install the original drive back to the unit and use as normal,
purchase a larger drive and follow "the zipper" instructions as written and you should have no problems hacking it,
go to this website and read what "the zipper" does and go to "Rbautch hack script" linked on the left and read what that does,
