Ok so today my friend got the 1tb seagate for 135 off craigslist new in the box from some guy who didn't need it. also we got this adapter off ebay http://cgi.ebay.com/PATA-IDE-TO-Serial-ATA...id=p3286.c0.m14
So after playing with xboxhdm and swapping his 500 gig with my 10's I put the 1tb in the xbox booted it to the stock dash fine. then i put the cover on and it constantly rebooted till i put mechassault in there and modded it again.
so after modding it the thing kept freezing on boot after many attempts but worked fine without the cover on.
so upon further investigation I found that when the case was screwed on the power cable was pushing the adapter down causing errors like 13 then 21 then 7 in random order. then sometimes it would boot to the dash (unleashed x) and the words would be all garbled.
but every time the case is off it works so first i ripped halo to the hard drive played it and it was good so . right now i'm transfering 150 gigs of data and still no problems but obviously i want to close the case and as such i'm looking for a new adapter to make this 1tb more stable than it is.
by the way the xbox is a version 1.0
the hardrive was set up with 2 469 gig 32kb cluster partitions using xbpartitioner if you'd like to know...
also does anyone know how to change the mac address since the way i changed the harddrives was to just unlock the 500 gig he had and lock it to put it in one of my spares so now his 1tb and 500 gig xbox have the some mac address so they can't be connected to transfer data at all.....
