GPT (GUID Partition Table) is a partitioning scheme that allows creating partitions on large hard drives (more than 2 TB). It supports up to 128 partitions per drive and uses 64-bit addresses to locate them. However, GPT is not compatible with older versions of Windows, such as Windows XP or Windows Server 2003, which use MBR (Master Boot Record) as the partitioning scheme. If a disk uses GPT, it may not be recognized or accessible by an older Windows server.
