How to Solve "Unable to Convert Dynamic Disk to Basic Disk" [2024 Updated Guide]

There are many issues when converting a dynamic disk to basic disk with Disk Management, which may stop you from converting dynamic disk to basic. This article will help you analyze the reasons and offer different solutions.

Why can't I convert a dynamic disk to a basic disk?

If you cannot convert a dynamic disk to a basic disk, the problem might be caused by one of the following:

1. The "Convert to Dynamic Disk" option is grayed out and unavailable.

This happens when you convert a disk larger than 2 TB to a dynamic disk. This is because Disk Management does not support disks larger than 2 TB in storage space. Otherwise, it shows as unallocated space.

2. Invalid package name

This is a known issue. If your computer name contains one or more double-byte characters, you might receive an “Invalid package name” message. This will prevent you from converting dynamic disks to basic disks.

3. Object does not support this operation

You may receive the "This operation is not supported by the object" message, because Dynamic Disk does not support USB or removable disk.

Insufficient available space on the disk.

If you can't convert dynamic disk to basic disk, you may receive the message "There is not enough space available on the disk to complete this operation." That's because at least 1 MB of unallocated space is required at the end of an MBR disk to create a dynamic disk.

5. Security features enabled

You might receive this message: "The disk cannot be converted to a dynamic disk because one or more partitions have the Secure Boot setting enabled." This is because you can't use dynamic disks on a system partition.

Above are the reasons that contribute to the inability to convert dynamic disk to basic disk. Now, let's move on to the solutions to these issues.

How to fix "Unable to Convert Dynamic Disk to Basic Disk"?

Now you know the reasons why you can't convert dynamic disk to basic disk, and for these reasons, I've provided 5 different methods.

When there is not enough space and the partition shows as read-only, Partition Master will give a low disk space warning and provide an option to "Resize with one click."

Click OK to automatically resize the partition.

With Partition Assistant, you can intelligently extend the partition to solve low disk space problem, and all you need is to click “OK” to continue.

If the Intelligent Resize option doesn't suit your needs, you can click Manual Resize to expand the partition manually, and then click OK to proceed.

Step 3: Perform the operations to extend the low disk space partition.

Click the “Run Task” button in the top right, and save all changes by clicking “Apply.”
