This article mainly introduces what are the differences between guid and mbr format, with a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let Xiaobian take you to understand.

The difference between guid and mbr format: 1, MBR has its own initiator, that is, startup code, while GUID partition table has its own backup, which saves a copy of the same partition table at the beginning and end of the disk; 2. MBR partition scheme can not support disks that exceed 2TB capacity, while GUID partition table can recognize the maximum 18EB.

Differences between guid and mbr formats:

1. The security of partition tables is different. MBR means "master boot record". It has its own initiator, that is, the boot code. once the boot code is broken, the system cannot be started, and the system can only be started through repair. On the other hand, the GUID partition table comes with its own backup, and a copy of the same partition table is saved at the beginning and end of the disk. After one of them is destroyed, it can be restored through the other.

2. Different disk capacities are supported. MBR partitioning scheme cannot support disks that exceed 2TB capacity, that is, 3TB hard drives are partitioned with MBR partitioning scheme, and 1/3 capacity will not be recognized. Partitioning with the GUID partition table (GPT) scheme can recognize the disk with the maximum 18EB (18X1024GB) capacity.

3. The number of zones is different. Hard drives that use MBR partition tables can only be divided into up to 4 primary partition disks, while the GPT partition table type is not limited by the number of partitions. The limitation is only in the operating system-Windows supports up to 128GPT partitions, and you don't need to create extended partitions.

4. The partition identity is different: GUID partition, each partition can have a name (different from the volume label).

Thank you for reading this article carefully. I hope the article "what are the differences between guid and mbr formats" shared by the editor will be helpful to you. At the same time, I also hope you will support us and pay attention to the industry information channel. More related knowledge is waiting for you to learn!
