I have a question (and maybe this has been answered already)... I just replaced my stock HD with a 200gig WD. Prior to this I had created my XBL account on my stock drive. When I fired up my new drive after setting it up (mod chip off ofcourse), my live account was not on my new drive so I did used the 'account recovery' feature. Now, this can be used so you can log in from a different xbox to play with your account. Would the revoery feature clear out the marriage info between the hd and eeprom? I was able to connect to live on my new drive, recovery my account, and edit my friends list with no problem (no modded xbox error).
I'm a little hesitant to play a game on it, I may end up just setting my box up so that I can easily swap between my stock drive nad my new drive.
