On MS-DOS IDE Mode Tested on two computers, Intel 4770k z97 impact VII and an i3 3220 intel dh61? mobo Sector checksum 0000 is wrong! comes up when trying to dump the 16-25 sectors. on other hdds "sector checksum e8da is wrong!" This is done on SATA.
It probably doesn't like the SATA chipset on your motherboard, hddhackr was fussy back in the day. The only device I could get it to work on when i made my own 500gb drive the other year was my old 10 year old MSI Wind Netbook. Also keep in mind the Xbox 360 does now support up to 2TB usb drives, where as when hacking hard drives was popular it didn't and the official MS drives were stupidly expensive in comparison.
