Are you looking urgently for a way to fix the cloned hard drive shows wrong size error? This article will describe how to fix a cloned hard drive showing the wrong size and offer a better cloning tool called EaseUS Disk Copy to help you clone a hard disk.
Many computer users have complained that they encounter the hard drive showing the wrong size after cloning. So why does a cloned drive show the wrong size? And how to fix this problem?
This article offered by EaseUS will explain the common reasons that can cause the cloned hard drive shows wrong size or the cloned drive not showing full capacity error and how to fix it. Let's come to the details.
To figure out why the cloned hard drive shows the wrong size, one should know the cloning principle first. Cloning allows you to duplicate both the disk's original structure and its data. In other words, the old hard disk and the cloned hard disk are identical.
When you upgrade to a bigger hard disk, you may find the partition size on the target disk will remain unchanged. In other words, the cloned drive is not showing full capacity.
This is because when cloning a hard drive, you clone not only the data in the drive but also the partition size. Therefore, if the target disk is larger than the source disk, most cloning software will leave the extra space on the destination as unallocated space. In addition, it is also possible that the cloning process was not executed correctly. As a result, you will encounter the issue that a hard drive shows the wrong capacity.
However, you cannot access the stored data or add new data to the unallocated space since it is invisible in Windows File Explorer. That is why the cloned hard drive shows the wrong size in File Explorer instead of Disk Management.
You need to shrink, extend, or transfer the current partition on the disk to the unallocated space for File Explorer to display the full capacity of the cloned hard drive. But how to resize or move the partition on your computer?
Fortunately, you can use Windows built-in programs, like Disk Management or Diskpart, to help you. Let us come to see how they can help you solve the 'cloned drive shows wrong size' error.
You can try shrinking the current partition using Disk Management to identify the "unshown" disk space and extending it to the entire size if the cloned hard drive shows the wrong size in File Explorer. Here's how to use Windows 10 or 11's Disk Management to resize or expand partitions.
How to Shrink Disk Partition
Step 1. Press Windows + R to launch the Run box. Then, type diskmgmt.msc and hit Enter.
Step 2. Right-click on the target partition and choose Shrink Volume.
Step 3. Enter the amount of space, such as 200, in the pop-up window, and click Shrink.
How to Extend Disk Partition
Step 1. Right-click on the partition and choose Extend Volume.
Step 2. Tap Next and choose the cloned disk.
Step 3. Adjust the space you want to extend the target volume. Click on Next > Finish.
However, some users argue they can't extend the partition volume because the extend volume option is greyed out. Under such circumstances, you can move to the following solution.
The Windows built-in utility Diskpart can also shrink/extend partitions. It is a command-line utility that lets you manage volumes, virtual hard disks, partitions, and disks. Here's how to use Diskpart to resolve the "hard disk shows the wrong size after cloning" problem.
Step 1. Launch the Run dialog box again, then type diskpart and press Enter.
Step 2. Type the following command lines in the pop-up window and hit Enter each time.
Step 3. You can extend the partition after shrinking the partition. Type the following command:
Step 4. Type exit to finish and close Diskpart.

1. Why is my cloned drive smaller?
This is because when cloning a hard drive, you clone not only the data in the drive but also the partition size. Therefore, if the target disk is larger than the source disk, most cloning software will leave the extra space on the destination as unallocated space.
2. Does a cloned drive have to be the same size?
No, it does not have to be the same size. You can clone a hard drive to a smaller SSD/HDD. You must ensure that the target hard disk can accommodate all data on the source disk.
3. Why is my SSD not booting after cloning?
