Basically I accidently wiped my Xbox 360 20Gb Hard Drive so i'm trying to reinstall the firmware to make it useable again.
Looking around the net I found the guide written by InsaneNutter here -
https://digiex.net/guides-reviews/c...b-sata-drive-work-xbox-360-xbox-360-slim.html
and going through it it all made sense but where I get to the point where I use hddhackr to reinstall the HDDSS.BIN file I get this error -

Any ideas?
