You are viewing the article What are MBR and GPT standard hard drives? How to check standard hard drive MBR or GPT? at Thptlaihoa.edu.vn you can quickly access the necessary information in the table of contents of the article below.
MBR (Master Boot Record) and GPT (GUID Partition Table) are two different partitioning schemes used for standard hard drives. These partitioning schemes determine how the data on a hard drive is organized and accessed by the operating system.
MBR is the older and more widely supported partitioning scheme that has been used for decades. It uses a 32-bit partition table to store information about the partitions on a hard drive. MBR has a limitation of supporting a maximum of four primary partitions or three primary partitions and one extended partition.
On the other hand, GPT is a newer partitioning scheme that was introduced with the UEFI (Unified Extensible Firmware Interface) specification. It uses a 64-bit partition table, allowing for larger partition sizes and an almost unlimited number of partitions. GPT also provides better data redundancy and error correction due to its backup partition table.
To check whether a standard hard drive is using MBR or GPT, you can utilize various methods depending on your operating system. For Windows users, you can open the Disk Management tool by right-clicking on the Start menu and selecting “Disk Management.” In the Disk Management window, right-click on the disk you want to check and choose “Properties.” Under the “Volumes” tab, you will find either “Master Boot Record (MBR)” or “GUID Partition Table (GPT)” listed as the partition style.
On a Mac, you can open the “Disk Utility” application from the “Applications” folder. Select the hard drive you want to check from the left sidebar and click on the “Partition” tab. The partition scheme (MBR or GPT) will be displayed next to the “Partition Map Scheme” label.
In summary, MBR and GPT are two partitioning schemes used for standard hard drives. MBR is the older and more widely supported scheme, while GPT is a newer scheme with advantages such as larger partition sizes and better data protection. You can check which partitioning scheme your hard drive is using through the disk management tools available on your operating system.
There are two common standards on hard drives today: MBR and GPT. Let’s find out with Thptlaihoa.edu.vn what are MBR and GPT standard hard drives, and how to distinguish each type!
What are MBR and GPT standards on hard drives? Pros and cons of each type
MBR and GPT are considered two popular format standards on portable hard drives today. The basic difference between these two formats is in how to import and export data, organize and partition the drive.
What is the MBR standard on the hard drive?
MBR, short for Master Boot Record , came into use in late 1983. The MBR format hard drive has some of the following characteristics:
- Supports all current Windows operating systems (Windows 10, 8, 7, …), especially works well on both 32-bit and 64-bit Windows platforms.
- Supports up to 2 TB hard drive capacity.
- Supports creating up to 4 primary partitions (split 4 drives).
MBR (Master Boot Record) is a special boot area containing Boot loader, this is a program that contains all information about the system boot process. Therefore, in some cases, a faulty MBR will make the user’s computer unable to boot up with the error code Miss MBR.
What is GPT standard on hard drive?
GPT stands for GUID Partition Table. This is a new standard, gradually replacing the MBR standard, some of the features of the GPT standard on hard drives are:
- Only support running on Windows 64-bit platform (does not support 32-bit Windows).
- Supports hard drives with capacities up to 256 TB
- Supports up to 128 primary partitions.

Should I use an MBR or a GPT hard drive?
After learning what two hard drive standards are MBR and GPT, many people wonder whether to use MBR or GPT hard drives on their computers. Thptlaihoa.edu.vn suggests you some points as follows:
Use standard MBR hard drive when:
- Hard drives with less than 2 TB capacity. If the hard drive has a larger capacity, you can still use the MBR partitioning standard, but you must use 3rd party software to support it, like GParted on Linux, or MBR4TB on Windows.
- There is no need to create too many partitions (split drives).
- Your computer is running the 32-bit Windows operating system.
Use a GPT standard hard drive when:
- Your hard drive is larger than 4TB.
- The computer boots in UEFI standard, installing Windows on the GPT hard drive is appropriate.
- Only use 64-bit versions of Windows.
How to check MBR and GPT . standard hard drives
It can be said that the GPT standard has more advantages and is gradually replacing the MBR standard. However, MBR is more compatible than GPT in some cases. Whichever standard you choose, you also need to know if your computer is using a GPT or MBR hard drive with the following way:
If your computer is running Windows operating system, you can use one of the following two ways to check the hard drive standard as follows:
Method 1: Use diskpart
Step 1: Press the Windows key combination (the key with the window icon) + R to open the RUN dialog box > Then enter the cmd and Enter command to access,
Step 2 : Enter the diskpart command, press Enter , then enter the list disk command and press Enter again.
Step 3 : If you see the GPT columnmarked with an asterisk (*) , your hard drive is in GPT format . If not , your hard drive is probably in MBR format .
Method 2: Use Disk Management
Step 1 : Press the Windows key (window key on the keyboard) > Type and select diskmgmt .
Step 2 : Right click on the hard drive (which you want to check) and select Properties
Step 3 : Switch to Volumes , look at the Partition style section and you will know what your hard drive is standardizing, as shown below is the MBR standard.
Linux operating system
For computers running Linux operating systems (Ubuntu, Linux Mint, Debian…), you can command parted , then type sudo parted -1
A frame as shown below appears, if the value of Partition Table is msdos , it means that your computer is using a standard MBR hard drive . If the gpt value appears, the computer is in GPT standard.
With the information shared above, hopefully, it will help you better understand the two current hard drive standards, MBR and GPT, as well as the advantages and disadvantages of each of these hard drive standards.
In conclusion, MBR (Master Boot Record) and GPT (GUID Partition Table) are two different partitioning schemes used for standard hard drives. MBR is the traditional partitioning scheme that has been used for many years, while GPT is a newer and more advanced partitioning scheme.
MBR partitions the hard drive into four primary partitions, with one of them being an extended partition that can contain multiple logical partitions. It uses a 32-bit disk addressing system, limiting the maximum size of a partition to 2 terabytes. MBR also includes a boot code in the first sector of the hard drive, which allows the computer to boot the operating system.
On the other hand, GPT is a more modern partitioning scheme that overcomes the limitations of MBR. It supports up to 128 partitions and uses a 64-bit disk addressing system, allowing for much larger partition sizes. GPT also includes redundant copies of the partition table, providing better data integrity and recovery options.
To check whether a hard drive is formatted with MBR or GPT, various methods can be used depending on the operating system. On Windows, you can use Disk Management or the command prompt utility “diskpart” to view the partition style. On macOS, you can open the Disk Utility and select the hard drive to view its partition information. On Linux, the “parted” or “fdisk” commands can be used to check the partitioning scheme.
In conclusion, understanding the difference between MBR and GPT is important when dealing with hard drives. Knowing how to check the partition style of a standard hard drive ensures compatibility and enables better decision-making regarding partitioning and formatting options.
