Okey nope2dope..
The only thing you know is that you can hook up
the Hd to a Pc and see the partition table. As far as i know,
no one has yet get a stock sata drive to work on the 360.
And still, if we got to clone the content to a stock sata drive,
we don't know if it is going to work, even if the partition is
identical to the Ms one. We don't know if the drive have any
special tricks in it's chip set, firmware or anything else, maybe
hidden sectors with information, fat tabels etc...
And, you dont know if the Hd is partialy locked (Yes, there is a
part of the Hd, 7 Gb i think, that is unused?
? as far as we know
right know. Could be anything on that part of the Hd.
The only way right now is: if you want a bigger Hd, you got
to by it from Ms, and they don't have it yet :-(
