Why Need Partition Hard Drive in Windows
Disk partitioning is a process of dividing a hard drive into several partitions - managing the hard disk drive by shrinking, extending, deleting, creating partitions, and changing partition size, label, even location, etc. Why do we need to partition a hard drive? Here are the common reasons to partition a new/existing hard drive:
- To make full use of hard drive space, splitting it into several partitions.
- Operating System update.
- The changes in computer and hard drive usage.
- The change of computer users needs.
Hard drive partitions first being prepared for saving data, games, system, etc., normally will be resized, moved, split, merged, or created into new partitions in a new format or new size in Windows 11/10/8/7 or dual boot system.
Partition a new hard drive: If you buy a new hard drive and it only has a C drive. Then, if you want to partition the C drive, you need to initialize it before using it. Then, follow the step-by-step tutorial to split it up.
Partition an existing hard drive: You'll need to resize/move disk space for the drive partition.

Hard Disk Partition FAQs
1. Is it important to partition hard disk?
Most computer users partition their hard disks for two primary reasons: to organize their files logically and to improve system performance. If you want to run more than one OS on your system, it is important to partition the hard disk.
2. What are the types of partitions in hard disk?
Partition types include:
- Primary: A primary partition can contain only one operating system. You can create multiple Primary partitions, but the maximum depends on the Operating System you are using. In Windows, you can create 4 Primary Partitions, but in the Linux Operating System, you can create as many as you want(Depending on the File Allocation Table - MBR). Each hard disk must have at least 1 primary partition.
- Extended: An extended partition does not hold an operating system or boot records, but it does allow for logical drives within the extended space. This allows for more than the four-partition limit of primary drives by allowing numerous logical drives within the extended drive space. Usually, we create only one Extended Partition in a hard disk and store all other Logical Partitions inside that, so if any Logical Partition gets corrupted, then it will not affect other Logical Partitions data stored outside the Extended Partition.
