       gptsync - GPT partition table to MBR partition table synchronisation


       gptsync [-q] [-t] device


       gptsync  reads  the  GPT partition table on device and synchronises the
       legacy MBR partition table  with  the  GPT  partition  table.  The  MBR
       partition table can hold only 4 partitions.

       Legacy bootloaders or operating systems that do not support GPT require
       an MBR partition table; this is typically the case when using  GRUB  or
       LILO on an Intel-based Apple machine.


       -q     Do not print any message, do not prompt to modify the MBR.

       -t     Truncate  partitions  starting  or  expending  beyond 2 TiB (MBR
              limitation).  Default is to ignore such partitions.
