How to Clone a Hard Drive on Windows, Mac, and Linux

To start cloning, connect both the source drive that contains your data and the target drive that will receive the clone. Before beginning the process, it’s often recommended to format the hard drive on the target device to ensure a clean, error-free transfer. This step ensures that DiskGenius can access both drives simultaneously, which is necessary for transferring all files and system data from one to the other.

Next, download DiskGenius from its official website and install it on your Windows PC. Since Windows does not have a built-in cloning tool, this software provides the functions needed to create an accurate and reliable copy of your drive.

Once installed, open DiskGenius to access its main interface, where all connected drives and their partitions will appear. This allows you to confirm that the software has detected both your source and target disks before proceeding.

From the toolbar or main menu, select Tools > Clone Disk to launch the cloning wizard. This begins the process of preparing DiskGenius to copy data from your original drive to the new one.

In this step, carefully choose the source disk you want to copy and the target disk where the data will be written. Double-check your selections, as the target disk will be completely overwritten once the cloning starts.

Enable the System Migration option to include Windows boot files if you are cloning your system drive. This ensures that your cloned disk will be fully bootable, making it possible to start your computer directly from the new drive.

DiskGenius allows you to adjust partitions on the target drive before cloning. This is useful if your new disk has a different capacity, since resizing ensures you can maximize available storage space.

After confirming all settings, click Start to begin the cloning operation. DiskGenius will then copy data from the source to the target disk according to the method you selected.

Before the process begins, you may be asked to confirm your choices and select between sector-by-sector cloning or file-level cloning. The option you choose will affect both the speed and accuracy of the clone.

Allow DiskGenius to finish cloning without interruption. Depending on the size of your drive, this can take anywhere from a few minutes to several hours, but waiting ensures that the copy is complete and error-free.

When the process is done, shut down your PC, disconnect the original drive if you are replacing it, and test the new drive. This final step confirms that the cloned drive works correctly, especially if it is intended to be used as your system’s boot drive.

Start by opening Disk Utility, which is the built-in macOS tool for managing drives. You can find it by searching with Spotlight or by navigating to Applications > Utilities. This tool provides everything you need to handle the cloning process without requiring third-party software.

In Disk Utility, highlight the drive you want to clone data onto (the destination drive), then click the Restore button. This prepares the destination drive to receive the exact contents of the original drive, meaning its current data will be completely erased.

When prompted, choose the source drive, the one you want to copy, from the drop-down menu. This ensures Disk Utility knows which disk’s data should be transferred to the target drive. Double-checking your choice here is critical, as the process will overwrite the destination drive entirely.

Disk Utility will now begin copying the data from your source drive to your destination drive. The duration will depend on the size of your data and the speed of your drives. Once the process is complete, you’ll be prompted to click Done, which confirms the cloning has finished successfully.

Finally, restart your Mac and boot from the newly cloned drive by holding the Option (⌥) key during startup and selecting the cloned disk. This test confirms that the clone is fully functional, especially if you’ve cloned your macOS system drive.
