"I have a project coming up in which I will need to clone a dynamic disk for backup and precautionary reasons. This pc is running windows 2003 small business server. It has two disks that are dynamic and have been mirrored in the windows disk management software interface. What would be the best way to clone a disk for the reasons given in this setup? The system is fragmented extremely badly, and the customer is worried that defragmenting may cause a system failure or data loss. So they have requested I do the above and then defrag the system. That's the madness behind the method.

Thanks in advance for the input."

How to Clone/Copy Dynamic Disk or Even Resize It

There are two ways to copy and clone Dynamic disk by using EaseUS Partition Master. One is to clone dynamic disk, and the other one is to copy dynamic disk. It's basically based on your needs of choose which way for cloning or copying the disk.

Clone Dynamic Disk

As a Windows user, the computer may pop up a low disk warning which means it is too small to store more data and information. To replace it by cloning dynamic disk to a larger disk might be the right way. 

If the dynamic disk that you want to copy contains mirrored volumes, you need to break the mirrored volumes by using Disk Management.
Also, you are not allowed to directly copy one dynamic disk to another disk. So you need to convert dynamic disk to basic first to gain a smooth process of cloning and upgrading dynamic disk.

Step 1: Select the source disk.

Open EaseUS Partition Master. Right-click the disk that you want to copy or clone. Then, select "Clone".

Step 2: Select the target disk.

Choose the wanted HDD/SSD as your destination.

Step 3: View the disk layout and edit the target disk partition size. 

You can select "Autofit the disk", "Clone as the source" and "Edit disk layout" to customize your disk layout.

Then click "OK" to continue. (The data on the target disk will be wiped, back up the data in advance.)


Step 4: Execute the operation.

Click the "Execute the operation" option and click "Apply" to start the disk cloning process.


After cloning the disk to another bigger SSD or HDD, you can then apply EaseUS Partition Master to convert the new disk to dynamic disk. Then, you've completed the whole process of cloning dynamic disk to a new disk.

Copy Dynamic Volume as Backup

If you want to copy single dynamic volume data as backup, you can refer to this method for a guide.


Step 1: Locate the volume

Choose the volume on the dynamic disk, right-click on it and choose "Resize/Move".

To extend a volume, for example, you need to follow the three steps to decrease a volume for unallocated space first. Next, use the same "Resize/Move" feature to drag your mouse to merge the unallocated space into the volume you wish to enlarge. 

After this, you can fully trust the protective backup of your dynamic disk or upgrade the original dynamic disk with the larger disk.

Resize Dynamic Volume

There are two ways that you can resize dynamic volume with the help of EaseUS Partition Master.

1. You can resize the disk partition on the basic disk after cloning the dynamic disk, then convert it to a dynamic one if it is needed.

2. You can also resize dynamic volume directly on the dynamic disk.
