Have you recently reinstalled the operating system or integrated a new drive? In any case, when setting up a new disk in Windows 10 or 8.1, you will be asked if you want to use MBR (Master Boot Record) or GPU (GUID Partition Table). If you came across this article, you might be wondering what the difference is between GPT and MBR when partitioning a drive. Well, we will explain the advantages, compatibility and limitations of these two styles, and finally we will help you choose the style that suits you best. A basic part of the
formatting process is partitioning, which essentially divides available memory into multiple regions. When partitioning, you will encounter a partition table, which boils down to one question: MBR or GPT? MBR (Master Boot Record) and GPT (GUID Partition Table) are two different ways of storing partition information on a disk. Whether you are using Windows, Mac or Linux, these are two solutions for partitioning. Some partition information is where the partition starts, allowing your operating system to know which sectors belong to which partition and which are bootable.
Although many people are proficient in partitioning hard disk space in operating systems such as Windows, it is not actually necessary. Any storage device can be used without partitioning the memory, as long as it has been formatted with a supported file system. So why are so many partitions created? Let's take a look at some advantages:
MBR is only suitable for disks up to 2 TB, and only supports four primary partitions. To create more partitions, you must convert one of the primary partitions to an extended partition and create logical partitions in it.
In fact, GPT is not subject to the same restrictions as MBR, and GPT-based drives can be larger. Unlike MBR, GPT allows an almost unlimited number of partitions, the obvious limitation is your operating system. For example, Windows allows you to configure up to 128 partitions on a GPT drive without creating "extended partitions".
On MBR disk, partition and boot data are stored in one location. If the data is overwritten or corrupted, this can cause problems. However, GPT stores multiple copies of this data on disk, making it a more reliable option if the data is corrupted.
MBR has no way of knowing whether your data is corrupted, in fact you will only see the problem when the boot process fails or the partition disappears. On the other hand, GPT stores CRC (cyclic redundancy check) values to check whether your data is complete. GPT will notice the problem and try to recover the damaged data from another area of the disk.
The short answer is that unless you are still using an older version of Windows, have 32-bit Windows installed, or have a motherboard that does not support UEFI boot, the best choice for you is GPT. Generally,
MBR and GPT are provided, but in principle, GPT has become a standard solution, supporting an unlimited number of partitions, and there is no size limit on storage devices.
Although not many partitions require more than four partitions, it is ultimately safer to use GPT. GPT disks use the primary backup partition table for redundancy and CRC32 fields to improve the integrity of the partition data structure. If your HDD is larger than 2TB, GPT is also more suitable for you, because if you use MBR, it can only use 2TB of space in a 512B sector hard drive.
If you are still using MBR, we recommend that you convert your existing MBR partition to GPT. To perform this operation on Windows, you can use the "Disk Management" tool to convert partitions:
Linux operating system (such as Ubuntu) users can use the gdisk program to convert partitions through the terminal.
Now that we have discussed the difference between MBR and GPT when partitioning the drive, it is worth clarifying again that you must continue to use GPT when configuring the drive. Of course, unless you are using a very old computer with an old version of Windows, but the GPT corner has too many benefits.
