FAQs on Cloning HDD to Smaller SSD using Macrium Reflect

Can Macrium Reflect resize partition?

Yes, Macrium Reflect supports manual and automatic resizing of partitions during the cloning process.

It depends on your objective:

  • Clone: Best when you're upgrading to a new drive and want an immediate bootable copy.
  • Image: Ideal for backups. You create a compressed snapshot of your disk that can be restored later.

For moving from HDD to SSD, cloning is the faster and more direct approach.
