Can Acronis Clone to a Smaller Drive?

Acronis (Acronis True Image, now known as Acronis Cyber Protect Home Office) is a powerful backup and disk cloning software. It has earned its reputation for offering a comprehensive toolkit for users who want to clone drives, perform regular backups, or restore data in case of disaster.

Yes, Acronis can clone to a smaller SSD, but there's a catch. Your data on the source drive must fit within the capacity of the smaller SSD. For instance, if you have a 1TB HDD with 800GB of used data, you can't clone it to a 500GB SSD unless you delete or move some data first. That is to say, Acronis cloning to smaller drive works well when:

  • The used space on your source drive is smaller than the destination SSD.
  • You adjust or exclude unnecessary files during the cloning process.
  • The source and target drives are properly partitioned, and file systems are compatible.

How to Use Acronis to Clone to Smaller SSD

The following is a step-by-step guide on how to use Acronis True Image to clone to a smaller SSD.

Before you begin:✎...
Backup important data just in case.
Ensure your SSD is properly connected via SATA or USB.
Clean up your source disk by uninstalling unnecessary programs and deleting junk files to make sure that your SSD has enough space for the used data. Or the Acronis clone may fail with errors like "Not enough space on target disk" and "Operation failed."

Step 1. Download and install the Acronis software on your device. Then, launch it and navigate to Tools > Clone Disk.

Clone Disk

Step 2. Select the Automatic (recommended) or Manual mode as needed. The former is suitable for most users, especially beginners, because it automatically adjusts the size of existing partitions to fit the target drive. The latter is more suitable for professionals.

Step 3. Select the source drive that you want to clone, and click Next. Then, choose the destination SSD.

Step 4. Choose the appropriate cloning method based on your cloning target.

Step 5. Review the cloning information and hit Proceed to let Acronis clone disk to smaller SSD.

That's all about how to clone with Acronis. While it is available to use Acronis to clone to smaller drive, this software has some disadvantages. For example:

  • Acronis cloning only supports basic disks (MBR and GPT partitions) and does not support cloning dynamic disks.
  • It requires that both the source and target disks have the same logical sector size, for example, 512 bytes per sector. You can check this in Windows System Information.

Easier Way to Clone Larger HDD to Smaller SSD

While Acronis is powerful, it may not be the easiest tool, especially for first-time users. If you want a more intuitive experience, AOMEI Cloner is a better choice. It is designed specifically for cloning and migrating OS and data.

This software runs in the Intelligent Clone method by default, which clones only the used space, making data transfer from larger drive to smaller drive a piece of cake. Also, it allows you to clone hard drive with bad sectors by skipping the bad parts.

AOMEI Cloner
Best System and Disk Cloning Software
  • Flexible cloning options: It offers Disk Clone to clone entire disk, System Clone to copy only system-related partitions, and Partition Clone to migrate just a particular partition.
  • Wide support: It supports different disk types, like SATA/IDE/PCIe/M.2/NVMe SSDs, so you can use it to clone HDD to SSD with different sizes and brands, and clone MBR to GPT or vice versa.
  • SSD Alignment: It can automatically align partitions on SSD to improve SSD performance and longevity.

Here are steps on cloning larger HDD to smaller SSD using AOMEI Cloner.

Step 1. Download and launch the disk cloning software, select Clone from the left pane, then click on Disk Clone.

👉Tip: If your used space is larger than the target SSD, you can use the System Clone option to migrate only OS to SSD, by leaving other data behind.

Disk Clone

Step 2. Select the drive that you wish to clone, and then select the connected SSD as the destination drive.

Destination Disk

Step 3. On the Operation Summary screen, enable SSD Alignment to accelerate the reading and writing speed of the target SSD. Then click Start Clone to clone larger HDD to smaller SSD with Acronis alternative.

FAQs about Acronis Cloning to Smaller SSD

#1. Can you clone a 1TB HDD to 250 GB SSD?

Yes, but only if the used space on the 1TB HDD is less than 250GB. You’ll also need to shrink partitions to fit the new drive. Acronis may struggle with this task unless you manually resize partitions. Tools like AOMEI Cloner handle this more reliably by copying only the data you need.

#2. Can I clone a 1TB HDD to a 500GB SSD?

Absolutely, provided that the used data on the HDD doesn’t exceed 500GB. A 500GB SSD offers more flexibility, but again, Acronis may not automatically resize partitions to fit. Use a cloning tool that supports intelligent cloning to make the process easier.

#3. Can I just swap SSD after cloning it?

Yes. Once the cloning is complete, shut down your PC, replace the old HDD with the SSD, and boot it up. Make sure to set the SSD as the primary boot device in BIOS if needed.

In the End

Cloning your existing drive to a smaller SSD might sound daunting, but it doesn’t have to be. Whether you choose Acronis to clone to smaller SSD for its powerful suite of tools or opt for AOMEI Cloner for a more user-friendly approach, both can get the job done.

Just remember:

  • Ensure your data fits within the smaller SSD.
  • Clean up and back up before cloning.

Choose the tool that fits your comfort level and needs.
