Windows XP does not recognize hard drives or RAID volumes above 2TB

Now the capacity of the hard disk is more and more, and the price is also getting cheaper, so buy a large volume of hard disk to store a variety of important data, but also the vast number of friends a very cheap choice, now the market has 3TB of large-capacity hard disk!

But for ordinary users, the use of Windows XP system should be more, according to statistics, the market share of Windows XP is quite high, in terms of speed, availability, software richness and compatibility stability, many friends will choose to use Windows XP system as its own choice, however, when using this system to increase support for a large-capacity hard disk, it is found that a hard disk or RAID volume that is larger than 2TB is not recognized, and Microsoft's official explanation is that it is necessary to use the latest GPT partition table to establish a hard disk partition for the operating system to be recognized.

I have a 2.2TB hard drive installed on my computer, but the operating system does not recognize the full capacity.

In addition, I have no way to create a partition larger than 2TB, this is why?

Due to the limitations of the Microsoft operating system, the operating system defaults to the MBR partition table to initialize the hard drive, but the MBR can only manage 2TB partitions or hard disks.

To establish or use a partition larger than 2TB, you must initialize the hard disk to a GPT (GUID Partition table) partition table.
GPT partitioned tables can manage up to 18EB of hard disk space (1EB = 1024PB = 1048576TB) and can manage up to 128 partitions.

GPT Partitioned tables can be

Windows 7
Windows Server 2008
Windows Server 2008 R2
Windows Vista
Windows Server 2003 SP1
Windows Server 2003 (64-bit)
Windows XP x64 Edition

or later operating system support. So in the use of more than 2TB and above the capacity of the hard disk, we must first consider their operating system is supported! If not, change Windows 7 or Windows Server 2003!
