I'm no expert on GPT but doesn't GPT also store some things at the end 
of the disk too?

The reason i ask is because I'm sure i once ran into problems with that 
when changing from GPT to MBR using tools that wasn't fully GPT aware 
and knew how to clear GPT.
i think i ended up with an MBR partition layout but with GPT leftovers 
and some tools complained.
