Okay, here is the totality of my situation...

My first Xbox died. And with that, the Maxtor Diamond 120GB HDD that was installed in it has been unrecoverable (I don't KNOW the password).

I do have the eeprom.bin made from the "backup" option of evox from that [dead] motherboard/xbox. (The "backup" was made off the stock drive when I first mod'd so the "hdddisablepassword" in it won't work for the 120GB, but for all my research, it appears the eeprom is a constant.)

Of course, there are no hash calculators that I know of for xbox versions over 1.1, but there are eeprom flashers (actually, Slayers will flash an eeprom from a .bin, I believe). So, if I flash my new Xbox's eeprom with the old boards eeprom.bin, I should be able to use my old 120GB HDD, right...?

Haha, I've learned more than I ever wanted to really know in the last week...
