The picture above in this post applies LBA 0, LBA 1, LBA 3, LBA 4 …… to represent disk drive address. To define the partition style as like its name GPT uses globally unique identifiers. GPT is a relatively new and latest partitioning style of a hard disk drive compared with MBR, and it is the better replacement of Master Boot Record. GPT is the short form for GUID ( Globally Unique Identifier) Partition Table which is another disk partitioning type. Partition information stored in 16-byte space includes 1. Users can now generate more than four logical partitions in an extended partition.

Windows discovered a solution named extended partition To eliminate this limitation. But many advanced users are not entirely satisfied with just four primary partitions and wish to create more logical drives or partitions to save data or distinguish between various kinds of data.

That means, Master Boot Record partitioning can only create four primary partitions. The entry for each partition is 16 bytes data, and the total size is 64 bytes. Master Boot Record provides a specific boot sector at the beginning of the hard disk drive, and it holds some information about the partitions. Many users use this disk style extensively with or without knowing about it.

MBR vs GPT Partition Layout MBR partitioning Layout for Disk:Īs noted above, MBR is the abbreviation of Master Boot Record which is an ancient style to handle or operate the partitions in a hard disk drive, and PC DOS 2.0 was the first Operating System (in 1983) with Master Boot Record partition style.

Here you probably are wondering to know that what are the main differences between MBR and GPT partition style? Which one is better for you if you are using SSD? Please keep reading the answer to your questions will be focused on. It’s not a huge mistake because, after a period you will find this partition formatting style again and you have an option to change your disk still to GPT partition style. Most operating systems even does not show any permission message, If windows show then most of the users straightly click “OK” to perform this initialization without choosing GUID Partition Table. The default option of Windows is to initialize to Master Boot Record. For the first time, If you connect an SSD(Solid State Drive), an external HDD (Hard Disk Drive), or other data storage devices in your personal computer, you should choose to initialize this method to either MBR or GPT). Before you first use a new replacement hard disk drive Windows will show a message asking about partition style, and the message is “ You must initialize a disk before Logical Disk Manager can access it” with selecting the “MBR” option. Abbreviation of MBR is Master Boot Record. MBR is another kind of partition table style. GPT is a standard for the layout of the partition table on a physical hard disk drive. Abbreviation of GPT is GUID Partition Table, and GUID means Globally Unique Identifiers. Keep reading if you wish to enrich your knowledge about this partition structures and their behaviors.įor most experienced computer users, I think they will come across the terms “MBR” and “GPT” more or less.

In this article, I will introduce some information and discuss their differences of MBR VS GPT in Windows 10/8/7/XP/Vista. If you are attempting to try and do some operations on your hard drive like partitions of various sizes, you will entirely come across the terms of “MBR” and “GPT.” It is hard to decide when facing the problem of having to convert disk style between MBR and GPT. As you know, the hard drive is essential of part of the computer to store everything. Nowadays with the revolutionary development of technology, the computer has become a necessary tool that is employed to cope with several things in life and work all over the world.
