Thanks for your help. In that case, will this be possible?The answer is no because:
-If you are on dashboard 13146 or higher, you will need the Probe 3 to extract the key to flash your drive.
-You will still need something that connects to the computer that will pass along the firmware. (X360USB PRO or SATA Card)
And, it's not recommended to power your drive using your Xbox 360 because in the event that it loses power, your drive will wind up with an incomplete firmware. (When worse comes to worse, you don't have your dvdkey and your drive is erased)
Wth? I'm not even asking for SATA support. I have a SATA card which I used to correctly flash a hitachi drive which works, it just the xbox that doesn't..but hey sounds like the answer your looking for is i have a spare sata port and molex hope it works, well if it does go ask elswhere like your pc helpdesk for the onboard sata connection and molex support
