Need to Convert a Dynamic Disk to a Basic Windows Server?

Organizing the disks into the appropriate partitions and locations is critical. A correctly designated space is not only convenient to use but also improves the system's overall performance. Disks are created by partitioning hard drives into subfolders and folders. There are two partition systems in the Windows operating system: Dynamic and Basic.

The disk partition system will be examined in-depth in this article. We will look at why the basic disk is preferred over the dynamic disk in more detail. Aside from that, we will explain the process of converting a dynamic disk to a fundamental disc using simple approaches. So let's get into details.

Use the fast and safe way.

Dynamic VS Basic: Why Choose Basic?

We will first look at the functionality and features of Basic Disk and Dynamic Disk individually.

Basic Disk

In the Windows operating system, this is the most common storage type. The logical partitions are made to manage all the data and folders on the hard disk. Three primary partitions and an extended partition with multiple logical drives make up the Basic disk. It provides a simple storage capacity that makes changing storage requirements easier to access.

The following are some of the significant features of a Basic disk:

  • It can create and delete primary partitions.
  • In an extended partition, it can create and delete logical drives.
  • It can format the partition and display it as an active disk.

Dynamic Disk

As the name implies, a dynamic disk allows you to modify the size of your partitions. It is more flexible than a basic disk. It does not use a partition table. For partition information, it uses a hidden logical disk manager and virtual disk service. The partitions are extendable.

The dynamic disk most notable features are listed below:

  • Simple, spanned, striped, mirrored, and RAID-5 volumes can all be created and deleted
  • Reactive missing offline disk
  • Repair mirrored or RAID-5 volume

A comparison of Basic Disk and Dynamic Disk is shown below:

                       Basic Disk                            Dynamic Disk  
It uses a normal partitions table. It uses a hidden logical disk volume. It has a dynamic storage volume.
All Windows operating systems, including MS-DOS, Windows 95, Windows 98, and Windows 8, are supported. It only supports Windows 2000, XP, 2003, 2008, 2011,2012, Vista, Windows 7, and Windows 8. It is incapable of supporting the older operating system.
Partition sizes are not changeable once they are created. You will require a third-party tool. Partition sizes are changeable without any data loss.
Each drive contains a further 3 to 4 partitions. It does have one secondary extended partition too. There is no limit for primary and secondary partitions.
It has two styles of disk Partitions 1. MBR and partition 2. GPT. It does not contain partitions. It has simple volume, spanned  volume, striped volume, mirrored volume, and RAID-5 volume.
It can easily be convertible to dynamic disk without data loss. To convert into a dynamic disk all the volume must be deleted. To avoid data loss you need to use third-party tools.

Now that we've identified the differences between Basic and Dynamic disks. We can go on to the next step. We can answer why to choose basic. The first and foremost important reason to use Basic Disk is that it works with all versions of Windows. Second, Windows has made the Dynamic Disk deprecated. It is no longer recommended to use.
