Abstract
In order to be used in a computer system, a hard disk drive (HDD) must first be
partitioned. Partitioning is done at the drive level and for many decades used the
Master Boot Record (MBR) partition method. A new method called GUID Partition
Table (GPT)) is now used for large-capacity drives. GPT al ows for volume sizes
much greater than 2.19TB, and therefore must be used on drives larger than the
MBR limit of 2.19TB. This white paper describes the rationale for GPT and the types
of OS, BIOS, driver, and SW tool support needed to successful y implement GPT
drives in desktop systems.
Why GPT?
HDD areal density (bits/sq in) and tracks per inch (TPI) continue to steadily
increase. For 2010, many typical desktop 3.5” hard drives have areal densities
and TPI that permit capacities up to 500GB per platter. In 2011, it is expected that
improvements in areal density and TPI wil allow drive manufacturers to begin
shipping drives that have capacities of1TB/platter. At this density, drives of 2TB
and 3TB capacities become more easily producible and hence cheaper and more
widely available.
