GPT (GUID Partition Table) and MBR (Master Boot Record) are two different types of partition tables used to store data on a physical hard drive. GPT is the newer standard, while MBR is the older one. GPT is more flexible and has better compatibility with modern hardware, while MBR is more compatible with older systems. When creating partitions on your Windows PC, you should choose GPT if your system is designed to work with it.
The MBR disk stores partition and boot data in one place, which can cause big problems once this data is corrupted or lost. On the other hand, the GPT disk keeps several copies of partition and boot data on the drive, making it more secure and robust. In addition, GPT stores the CRC (cyclic redundancy check) values so that it can detect if the data is corrupt and try to restore corrupt data from other copies. Windows 11 operating system is designed to run in the GPT partition style, and you should choose GPT when asked when creating partitions on your Windows PC.
The MBR protector of a GPT disk performs the function of preventing tools that only support MBR disks from erroneously recognizing and overwriting GPT disks. If a computer uses UEFI, it will only support GPT as a system disk, especially since Microsoft officially announced that the Windows 11 system will only support GPT and UEFI. For example, if you prefer a faster boot time, it is recommended to use a GPT disk as the system disk; if the computer is BIOS-based, choose MBR as the system disk; while if you use a disk smaller than 2 TB for data storage, both GPT and MBR work well. Note that only new operating systems can use the GPT disk; for example, Windows XP 32-bit does not support the GPT disk. Therefore, before making a decision on which partition table to use for your system, you should know if your system is designed to work with GPT or MBR.
