Can I clone a larger HDD to a smaller SSD?

"Lately, my desktop runs extremely slow and I want to do something to optimize its performance. The first idea I came up with is to upgrade the machine from the old HDD to a new SSD.

However, I found that many stand-alone cloners don't allow to clone larger HDD to smaller SSD. I used 500 GB HDD and the new SSD is 256 GB.  And the smaller SSD is far beyond the used space on the HDD. Can I just move the user data by cloning HDD to SSD? "

With faster writing and reading speed, being quieter, SSD becomes hot among users. Most people choose to move hard disk data to an SSD. As we all know, SSD is designed with a smaller capacity than that of HDD.

When it comes to cloning a larger HDD to a smaller SSD, people have difficulty in finding a proper cloning tool that can resolve the larger to smaller cloning issue. If you are having the same trouble, stay calm. On the following, you will find detailed guidelines to get rid of this issue, transferring everything from the old HDD to the new SSD.

# 2. Prepare the SSD

  • First, make sure that your SSD capacity is bigger than the used space on the HDD. 

If the HDD usage is bigger than the SSD capacity, you won't be able to clone the bigger HDD to the smaller SSD. To do so, you may need to delete or clean useless large files from the HDD in advance. 

  • Next, clean up SSD, leaving it unallocated.

To avoid cloning errors, we suggest you delete all partitions on the SSD disk, leaving the whole disk unallocated.

With the following tutorial, you can clone a 1TB HDD to a 500GB SSD or clone a 500GB to a 250GB SSD without any limitations. Once again, to clone bigger HDD to a smaller SSD disk, you need to confirm that the actual data usage space on the HDD is equal to or smaller to the SSD capacity. Then EaseUS Partition Master will clone all data to your new disk.

Now let's learn how to copy data from a larger HDD to a smaller SSD:

 

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 4: Execute the operation.

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

Notice:
If the source HDD is a MBR system disk, EaseUS Partition Master will diagnose whether your system support UEFI boot. If yes, the target SSD will a GPT disk and you need to change its boot sequence in BISO. 
If the source HDD is an MBR data disk, the cloned SSD will be MBR.
If the source HDD is a GPT system disk, after the cloning, your SSD disk will be GPT without any boot issue.
If the source HDD is a GPT data disk, the SSD will be GPT too after the cloning. And you don't need to do anything.  

If your system support UEFI boot and the SSD turned into GPT after the cloning, follow steps here to change BIOS boot order and make your PC bootable:

Step 1. Insert the SSD to your computer, restart PC and press F2/F12/DEL to enter BIOS.

Step 2. Go to the Boot section and use the arrow key on your keyboard to set Windows boot from the SSD.

Step 3. Save the changes and restart your computer.

After this, your data and system will be visible and work on the new SSD again.
