Updated by Cici on Nov 02, 2022

There are many problems that arise when using Disk Management to convert dynamic disks to basic disks. These problems can make you unable to convert dynamic disk to basic. This article will help you to analyze the reasons and provide you with different solutions.

Why You're Unable to Convert Dynamic Disk to Basic?

If you are unable to convert dynamic disk to basic, it may be caused by the following reasons:

1. Convert to Dynamic Disk Greyed Out

This situation occurs when you want to convert a disk over 2TB to a dynamic disk. This is because Disk Management does not support disks that are more than 2TB of storage space. Otherwise, it will show as unallocated space.

2. The Pack Name is Invalid

This is a basic error. If you name your computer with one or more double-byte characters, you may get the message "the pack name is invalid." This will prevent you from converting dynamic disks to basic disks.

3. The Operation Is Not Supported by the Object

A message: "The operation is not supported by the object" may appear. That's because dynamic disks don't support USB or removable disks.

4. Not Enough Space Available on the Disk

If you are unable to convert dynamic disk to basic, you may receive a note: "there is not enough space available on the disk(s) to complete this operation" because you need to have at least 1MB of unallocated space at the end of the MBR disk for the dynamic disk. 

5. Security is enabled

You may receive this message: "The disk could not be converted to dynamic because security is enabled on one or more partitions." Because you could not use the dynamic disk on the partitions where your systems are.
