Cloning a drive creates a copy of its partitions and data on another storage device. It is useful when migrating to a larger SSD or replacing a failing drive, but cloning is not a substitute for a separate backup because changes to the source can also be copied to the destination.
Prepare the Source and Destination
- Back up important files to a separate location before cloning.
- Connect the destination drive and confirm its capacity is sufficient.
- Identify the source and destination by model, capacity, and connection so they cannot be confused.
- Save BitLocker or device-encryption recovery information before changing storage.
Choose Trusted Cloning Software
Use a current cloning application from a reputable developer and verify that it supports your Windows configuration and the source and destination drive types. Avoid random download sites and modified utilities.
Select Source and Destination
- Open the cloning tool.
- Select the existing Windows drive as the source.
- Select the new drive as the destination.
- Review the partition layout and confirm the destination can hold the selected data.
Run the Clone
- Start the cloning operation.
- Close applications if the cloning software recommends doing so.
- Do not disconnect either drive while data is being copied.
- Allow the tool to report completion before shutting down.
Boot from the New Drive
- Shut down when the cloning software instructs you to.
- If replacing the old drive, install or connect the new drive according to the manufacturer’s instructions.
- Use UEFI boot settings or the manufacturer’s supported boot-order controls if Windows does not start from the intended drive.
- Verify Windows, applications, files, and activation before wiping the old drive.
Do Not Wipe the Source Too Soon
Keep the original drive intact until you have verified that the cloned system boots and your important data is present. A clone is a migration copy, not proof that every file has an independent backup.
Summary
Back up first, identify source and destination carefully, clone with trusted software, verify the new drive boots, and keep the original until the migration is confirmed.
