When you initialize the new hard drive with Disk Manager default, on Windows 10, Windows 8, or Windows 7, a window pops up and asks you to choose between the MBR (Master Boot Record) and GPT (GUID Partision Table) disks.
What is the difference MBR and GBT on the disk partition? What are the advantages of each of the partition table?
As we know, the new hard disk must be initialized before you can partition for data storage. So, when you install a new hard drive to the computer, it will first initialize the disk and prompts you to choose between MBR and GPT partition to the system.
Most of us will click next step without knowing one of the advantages or disadvantages between MBR and GPT. However, the default settings of Windows will initialize the disk to the system partition MBR or GPT you may choose. Someday, you may find that your choice is not appropriate because it does not meet your needs.
Difference Between MBR and GPT on the Hard Drive
MBR stands for Master Boot Record, the disk layout is longer and more often used. While GPT, short for Global Unique Identifier Partition Table is a new disk layout associated with UEFI.
You probably know about the MBR, such as how to fix the MBR, which leads you to think MBR only refers to certain important data. Actually, MBR and GPT also specify style between MBR and GPT disk. After initialization, we can choose as disk MBR or GPT disk.
The difference between them is caused by the rapid development of the information age. Older systems show more weakness, thus introducing a new system to adjust for changes. After the hard disk is initialized, the structured information will be recorded and stored for a certain segment of the disk. On the other hand, the information will change with changes in the partition information, so-called partition scheme.
In detail, the organization in the MBR partition table maximum limit disk storage space only 2 TB (232 × 512 bytes). And only supports up to four primary partitions, or three primary partitions and one extended partition combination.
However, with the advancement of age, a larger storage device needs to be applied to the field of computers. Therefore, the MBR-based partition scheme will be replaced by a scheme GUID Partition Table (GPT) on a new computer, because it supports GPT disk partition table disk with 512- byte sector, which would be 9.44 ZB – zettabytes, 1 ZB is 1 billion terabytes, and the ability to have up to 128 primary partitions.
A GPT can coexist with the MBR to provide some form of limited compatibility with older systems.
￼Are you confused by the concept and the science behind MBR and GPT? Maybe you just want to know difference between MBR and GPT on the hard drive and how to identify what your disk use.
How to check if your hard disk MBR or GPT
There are two methods to determine the system hard disk partition that you are using. The first is the Disk Management Windows installation. The second is a command line DISKPART .
Method 1: Use Disk Management
Open Windows Disk Management, press ” Windows key + R ” to open the Run menu, enter ” diskmgmt.msc ” into the box, and click OK.
Select the disk (in this example, Disk 0) are scanned. The trick is to right-click and select ” Properties “.
￼ Step 3:
Select the ” Volume “. In the line “Partition style”, you’ll know whether your disk is MBR or GPT.
Besides Disk Management, you can also check it using DISKPART in Command Prompt.
Method 2: Using the command line on DiskPart
Step 1 :
To start DiskPart, click the Start menu and type ” diskpart ” in the search box. DiskPar right-click and select ” Run as administrator “.
Type ” list disk ” command and press Enter. Will display all disks connected to your computer. If the disk is GPT, it will display an asterisk (*), under the “Gpt”. If the disk is the MBR, it will be empty under the column “Gpt”. In this example, the Hard Disk 0 is the MBR disk.
MBR vs GPT: Which to choose?
Be careful when creating partitions on the disk MBR 5. If you want to create more partitions, you must create a structure no more than three primary partitions plus an extended partition logical partitions that are in the extended partition. Otherwise, the disc will be converted to dynamic disks. It is not recommended for ordinary users because some users may experience a dynamic disk. The issue was not valid and can not install the operating system on a dynamic disk.
In short, you may notice that the GUID partition scheme have more advantages, does that mean you can adopt this type of partition for each disk? No, not all Windows systems support this partition scheme.
Windows XP 32-bit, Windows 2000, Windows NT 4 or Windows 95/98 can not read, write, and boot from GPT disks, they will only read the disk MBR.
Windows XP x64 Edition can use a GPT disk for data only.
All versions of Windows 10, Windows 8.1, Windows 8, Windows 7, Windows Vista, Windows 2003 Server, Windows Server 2008 (R2), Windows Server 2012 (R2), and Windows Server 2016 can use the GPT disk partition for data. Booting is only supported on 64-bit editions on UEFI-based systems.
When you encounter these conditions, you can mix GPT and MBR disks on the system that supports GPT. However, the system requires the support UEFI boot partition must reside on a GPT disk. Other hard disks can be either MBR or GPT.
That’s the main difference between MBR and GPT disk. Hopefully now you can choose GPT or MBR, depending on what you have and what you need to do.
