So If you have a hard drive that you would like to use and it is 2 TB or smaller, select MBR when you initialize the hard drive for the first time. In case the data is overwritten or corrupted, the GPT partitioning method allows to restore it and make the operating system functioning again (you can’t do that using MBR disk). Among the main features of GPT is that it gives the ability to store multiple copies of the data within the OS. The GUID Partition Table (GPT) hard drive gives you more exciting features than the traditional Master boot record (MBR) hard drive, this is a newer and more convenient partitioning method.

Thre is no limit 2TB hard drive issue, as GPT partition table support maximum 9400000000 TB, with sector sizes of 512 (the standard size for most hard drives at this time). As such, if you have a 3 TB hard drive and you use MBR, only 2 TB of your 3 TB hard drive will be accessible Or usable.Īnd to Remedy this issue GPT partition table introduced, Where G stands for GUID (Globally Unique Identifier), and the P and T stand for Partition Table. The maximum hard drive size of MBR is 2 TB. This was the default partition table format before hard drives were larger than 2 TB.

MBR (Master Boot Record) is an older partition structured that was first introduced in 1983 And developed for IBM PCs.
