Commodore4Eva, the hacker behind the modified firmware releases on the original Xbox, and the Xbox 360 Samsung drives, has released a firmware that allows Xbox 360 users with the Hitachi DVD-ROM drive to play backup software. Both current drives should now be able to be modified to run backups, and there are several firmware swapping mod solutions on the way that will take advantage of this. This particular firmware is for the 47D version of the Hitachi drive, and a release for the 46 version should be coming soon. The hack is definitely not one for novices, and of course, will void the warranty of your Xbox 360.
