GPT versus MBR

GUID Partition Table (GPT) is the next generation of a hard disk partitioning scheme developed to lift restrictions of the old MBR. Being a part of the Extensible Firmware Interface (EFI) standard proposed by Intel to replace the outdated PC BIOS, it offers a number of crucial benefits:

 

q       Up to 128 primary partitions for the Windows implementation (only 4 in MBR);

q       The maximum allowed partition size is 18 exabytes (only 2 terabytes in MBR);

q       More reliable thanks to replication and cyclic redundancy check (CRC) protection of the partition table;

q       A well defined and fully self-identifying partition format (data critical to the platform operation is located in partitions, but not in un-partitioned or hidden sectors as this is the case with MBR).

 

Please note, that the current version of the product provides a limited support of GPT disks:

 

q       Backup of a separate partition or entire hard disk;

q       Restore of a partition archive to any location, even to a block of smaller size taking into account only the amount of actual data of the image (restore with shrink);

q       Restore of a hard disk archive to its original location or a larger disk without the resize function;

q       Create partition;

q       Format partition;

q       Delete partition;

q       Check file system integrity;

q       Test surface;

 

Besides, you won’t be able to see a drive letter assigned to a GPT disk in the program’s interface.
