Unmodded xbox with dead HDD

[Nybbas]

I have an unmodded japanese xbox (rev 1.0) with a dead HDD. I also have a working HDD from a USA xbox (rev 1.6) that has a softmod on it. If I extract the eeprom from the xbox with the dead HDD, can I use fatxplorer 3 to unlock the working softmodded HDD, then relock it with the extracted HDD password from the eeprom? Or would the xbox not read the new HDD because the model and serial numbers don't match the original eeprom?

I've found one tutorial on how to setup the new HDD with the extracted eeprom but that tutorial uses a spare xbox and will format/clear the new HDD, which I do not want since it's already formatted correctly and has a lot of games on it.

Any help would be appreciated

yes

you need both Xboxs' eeprom.bin files.  Unlock the current softmodded HDD with the 1.6 Xbox's eeprom.bin then use the unmodded Japanese Xbox's eeprom.bin to relock it for that Xbox.  

It's not the password that you are obtaining within the eeprom.bin file but an encryption key that along with the hard drive's model and serial number computes the correct password to lock the hard drive.

Thank you for the help!

I got a little bit confused because I wasn't sure if fatxplorer is able to figure out the password with the eeprom.bin. Now to wait for the rest of the parts to arrive in the mail.
