Cloned Hard Drive Is Not Showing Full Capacity. How Do I Fix It

I had cloned an SSD with about 5 partitions from another HDD. The boot was not working, so I re-did the boot and Windows partitions with Clonezilla.

Along the way, I got distracted or misclicked during the setup, I ended up with 2 partitions, with only 465 GB out of the total 2 TB.

I tried using diskpart to shrink/expand the partition but can't get past the 465 GB. Disk Manager only shows the disk as 465 GB and no extra unallocated space. The SSD is a SATA Teamgroup; the HDD was a WD. Another thing I noted is that the SSD shows the label in properties as if it was the HDD (which is 1 TB, so it is messed up it shows 465 GB)

Tried EASUS and Mini partition wizard to fix using the same method and re-sizing, extend/shrink partition but it was no different than using diskpart of disk management.

Any ideas on how to fix this?

Edit: I also formatted the SSD, which still shows the wrong size. I pretty much gave up on the data as I would re-clone the HDD after fixing the SSD. from Reddit

1] Make Full Use of Disk Capacity with EaseUS Partition Master

The primary reason why a hard drive does not show its full capacity after cloning is that the disk cloning software or disk owner themselves forget to adjust the disk layout as auto-fit. Then, the disk is cloned the same as the source disk; extra free space is left unallocated on the target disk.

So, you can use the EaseUS Partition Master for help, as this software allows people to flexibly make full use of the free space on the cloned disk by extending the volume or creating a new partition on the drive.

#1. Extend Volume with Unallocated Space

Step 1. Shrink partition to free up space to extend partition.

If the hard drive has enough unallocated space to extend the target partition, jump to Step 2, and continue. If not, free up space first:

  • At the Partition Manager section, right-click on a partition next to the target partition and select "Resize/Move".
  • Drag the partition ends to free up space, leaving enough unallocated space behind the target partition, click "OK".

2] Use Full Capacity of the Cloned Disk with Disk Management

Windows Disk Management is a Microsoft Windows software application that provides a graphical interface for disk management. It is used in computer systems to manage disk drives and partitions. The primary purpose of disk management is to optimize disk space usage and system performance.

So, you can use Disk Management to unallocated space in the target disk to extend a neighbor volume. Follow the guide given below to accomplish the operation:

Step 1: Press the Windows + R keys, type diskmgmt.msc, and click "OK".

Step 2: Right-click the partition in the Disk Management window and select "Extend Volume" from the context menu.

Note: If the Extend Volume option is grayed out on your PC, skip this method and move on to the next one to extend your disk drive's volume.

Step 3: Click Next and select the cloned disk.

Step 4: Modify the space where you want to increase the desired volume. Select Next > Finish. Adjust the space you wish to use to increase the desired volume.

If you tend to extend a non-adjacent volume with unallocated space, use the EaseUS Partition Master tool for help. Also, you can share this manual method to help some advanced users online:

 

3] Extend Cloned Disk to Full Capacity with Unallocated Space via CMD

Are you familiar with Windows computing skills? If so, you can use Command Prompt or CMD DiskPart to extend the unallocated disk space with command lines. It is a command-line tool for managing volumes, virtual hard disks, partitions, and disks. You can use certain command lines to manage volumes, partitions, etc. Follow the steps given below:

Step 1: Press the Windows key + R, type diskpart, and click OK.

Step 2: In the DiskPart window, copy and paste the command lines given below and press Enter after typing each command line:

  • list disk
  • select disk X (x refers to the target cloned hard drive, e.g., select disk 2.)
  • select partition X (replace x with the disk number you want to shrink its volume, e.g., select partition 2)
  • extend desired=X (replace x with the amount of space you need to extend in MB, e.g., extend desired = 100)

So, this is how to extend the target disk with unallocated space via Command Prompt diskpart.
