After the disk is repartitioned, operating system can be installed to a separated partition. If hard drive contains a single partition, you may want to add more partitions for different types of data. Some laptops comes from factory with a single partition, which means there is only one drive (C:) under My Computer. This part summarizes several reasons that you might need to partition a hard disk: When do you need to partition a hard drive? Besides, GPT disk performs CRC32 checksums to check corruptions and errors for partitions.

There is also a Protective MBR on the first sector of the GPT disk, so that a BIOS-based system can boot from a GPT disk via a boot loader stored in the protective MBR's code area. Thus, you can recover data from the backup information when the primary table gets corrupted.

The GUID partition table scheme stores partition table information in Primary PGT header at the beginning of the hard disk and a backup called secondary GPT header at the end of the disk. Each partition on GPT disk can contain up to 2^64 blocks in length, which is 9.44 ZB. In theory, you can create unlimited numbers of partitions on a GPT hard disk, though many operating systems restrict it to 128 partitions. GPT disk relates to UEFI which will replace the old BIOS, thus you can use GPT on a UEFI-based system.

GPT (GUID partition table): GPT is a newer partition standard, using GUID (Globally Unique Identifiers) to describe partition, which is going to replacing MBR gradually.

Once MBR is corrupted due to certain, partitions may get lost or the entire disk may become unreadable. Besides, MBR is the only place to store partition information. The shortage of MBR partition scheme is that it is able to manage up to 2TB capacity, thus it is not suitable for larger hard disks. To create more partitions, you can set one of the primary partitions as extended partition where you can create multiple logical partitions. On MBR disk, there can be 4 primary partitions (or 3 primary partitions and 1 extended partition) at most. Besides, MBR holds a bit of executable code which plays important parts in booting system. MBR is located at the very beginning of storage device, recording information for partitions.

MBR (Master Boot Record): MBR is the traditional approach of organizing partitions for hard disk and it is widely used now.

Currently, there are two classic partitioning schemes: MBR and GPT.

Some computers only contains one drive (C:) where installs operating system and applications, and stores user's data other users would like to create two or more partitions, installing Windows and programs in drive (C:) and store personal data to additional partitions, such as D: and E.ĭuring disk partitioning, you will be asked to which partition scheme to choose. There are two common ways to partition a single disk on Windows computer: single partition and multiple partitions. The main reasons we partition a hard disk is to organize space and data. The hard drive being partitioned is a single physical disk, but we can see divided areas appearing in Windows. What is disk partitioning? In short, it is splitting a hard drive's logical storage into multiple drives with each takes up a portion of usable storage. This section we will talk about basic information about hard disk partition and why you might need to partition a hard disk or USB drive. If you want to partition or repartition a hard drive, keep reading to find proper solutions.Ībout partitioning a hard drive in Windowsĭisk partitioning is one of the common operations we should know about, as it relates hard drive performance and data safety. Partitioning a hard drive is the process of dividing a disk into one or multiple sections and proper partition can aid performance.

In this article you can find three step-by-step methods to partition a hard drive in Windows 10/8/7, such as partition a hard drive with Disk Management and partition manager software.
