This protective MBR ensures the old tools won't mistake the GPT drive for an unpartitioned drive and overwrite its GPT data with a new MBR. But it was then soldered to the AVR (no socket so no easy transport back to the PC) and read/write experiments have already been done. Shatskih wrote: > The card can have the MBR partition table.
