I greatly appreciate the help, however I don't believe that will avert the need to reapply the System Update in my case. But tried this, I effectively followed this tutorial here:http://www.xboxhacke...11600#msg111600
Essentially FTPed over all my HDD1 and HDDX from XexMenu. Format new drive. Apply HD Compat and then FTP back.
However after that my Mass Effect 3 profile was borked and the avatar update had to be applied again as it was now gone. I just stuck my orig 20gB back in as I didn't want to lose my progress.
I suppose I could try again and just suck up trying to find the 13599 update again, but I would rather not. I'd rather just find a way to 1:1 update. Looks like I'll be following a hex editor tutorial with offsets. I don't believe FTP can do a 1:1 copy without the need to reapply updates.
