How to Change Dynamic Disk to Basic Disk Safely
Applies to: Windows 10/8.1/8/7/XP/Vista, and Windows Server 2000/2003/2008/2012/2016/2019.
There are two types of disk storage types on Windows: basic disk and dynamic disk. Many users are dithering which one to choose before partitioning a drive. First of all, you need to understand the features of the two disk storage types.
What Is Basic and Dynamic Disk?
Basic disk refers to a disk that is initialized for basic storage. A basic disk usually contains partitions, including primary and logical volumes, for file storage. And the created partitions are formatted with a file system - NTFS by default.
Dynamic disk is more like a disk that has been initialized for dynamic storage. It provides the features that basic disk does not.
Basic vs. Dynamic, Which Is Better?
Some of you may not know the differences between Basic and Dynamic disks. Here is a comparison table that may help you understand which is better and select the right disk type:
|Comparison||Basic Disk||Dynamic Disk|
|Maximum Partition Number||
According to this comparison table, basic and dynamic disks mainly share differences in OS, number of partitions, partition types, usages. It's obvious that Dynamic disk is mainly used for huge storage, while the basic disk is better for ordinary data storage.
Is It Possible to Convert Dynamic Disk to Basic Disk
Yes. You can convert a dynamic disk to a basic one.
The basic disk can be directly converted to a dynamic disk using the Windows disk management tool. However, you cannot directly convert a dynamic disk to basic when there are partitions on it.
To do so, you will need to delete all the volumes and data on the dynamic disk, which is the last thing you want to see. And the conversion is irreversible.
