Disk device compatibility

In accession to the accepted PC deejay allotment scheme, which uses a adept cossack almanac (MBR), EFI works with a fresh administration scheme: GUID Allotment Table (GPT). GPT is chargeless from abounding of the limitations of DOS MBR. In particular, the DOS MBR banned on the cardinal and admeasurement of deejay partitions (up to 4 partitions per disk, up to 2.2 TB (241 bytes) per disk) are relaxed.12 GPT allows for a best deejay and allotment admeasurement of 9.4 ZB (273 bytes).1213 The EFI blueprint does not appoint any accurate book system. The alone Microsoft Windows versions that can cossack from disks beyond than 2.2 TB are 64-bit versions of Windows Vista and after applicant operating systems, Windows Server 2008 and later, and the Itanium versions of Windows Server 2003 and Windows XP.
