What is the difference between primary / extended partition and logical drive?

I am often asked about the difference between a primary partition and a logic. In this post do my best to explain the difference between the two.

If you open Disk Management in Windows (Start – type diskmgmt.msc ) you will see your unit volumes and their corresponding partition type under the column State .

Most partitions are primary partitions. If you have more than one partition, the first usable partition (one that can contain data) is almost always a primary one. Primary partitions are marked with a dark blue strip by default.

The old school approach of having only one primary partition, followed by an extended partition. This is no longer necessary for NTFS volumes; in fact, if you are configuring a dual-boot system, each OS must have its own primary partition. A traditional disk can have up to four primary partitions or three primary partitions and one extended partition.

The partition extended a holdover of the previous days and was used when a drive has two or more partitions. In reality it does not contain data, it simply serves as a container for one or more logical units.

Extended partitions and logical drives are now more or less obsolete (the Windows Disk Management tool can't even create them), but Windows still shows the labels when creating a new simple volume.

The extended partition, by default, shown as a dark green outline surrounding all logical drives. If you have a drive with an extended partition, each volume inside is called a logical drive. By default, logical drives are identified in blue. You can create all logical drives up to the number of drive letters available on the system.

So, do you have to worry about creating multiple partitions or logical drives? Well, the main reason for creating partitions logically separate different types of data. always a good idea to have one partition for your Windows installation / system files and another partition for your data files. If the Windows partition becomes corrupt or inaccessible for any reason, you should still be able to access the data partition (unless the hard drive is physically functioning and both partitions are on the same drive).

Another basic reason for multiple partitions if you need to install another operating system, such as Linux, on the same disk. With separate partitions, each operating system can use a different file system and do not interfere with each other.

If there are multiple hard disks on the system, you can also use multiple partitions to optimize the paging file and speed up performance. If you have any questions, feel free to comment. To enjoy!
