Complete Guide to Cloning a Hard Disk: Steps for Secure Backups

This guide will explain how to clone a hard disk, an operation useful for transferring data and programs between computers or creating complete backup copies. Cloning allows you to exactly duplicate the contents of a disk, including the operating system and settings, onto another medium. This is particularly advantageous for emergency recovery or installation on new machines.

Cloning is an efficient alternative to using DVDs or USB drives, offering a faster and more reliable method for managing data. Thanks to specific tools, the process is simple and accessible even to non-expert users.

This guide is aimed at those who want to protect their data, migrate to a new computer, or simply have a complete backup copy of their system.

Prerequisites

Here is the hardware and software needed to clone a hard disk:

• Destination hard disk - An external or internal disk where to clone the data. It must have capacity equal to or greater than that of the source disk.
• USB box or connection cable - Necessary to connect the destination disk to the computer. It can be a 3.5” box with SATA input, a 2.5” box with SATA input, an M.2 box for SSDs, or a connection cable from SATA to USB-A or USB-C.
• Cloning software - Programs like File History (integrated in Windows) or Macrium Reflect X Home (to download and install).

Preliminary operations

To clone the contents of the internal disk to another, make sure the destination drive is connected to the computer. If the disk is not internal, get an appropriate USB box.

• For 3.5” mechanical disks (desktop PCs), use a 3.5” box with SATA input.
• For M.2 SSD disks, use an M.2 box.
• For 2.5” SSD disks with SATA 2 connector, use a connection cable from SATA to USB-A or from SATA to USB-C.

Insert the disk into the box or connect it to the dedicated cable and connect it to the computer. Turn on the box and wait for the operating system to recognize the disk.

How to clone a hard disk with File History (Windows)

Open the Windows Start menu, type "file history" in the search field, and click on Control Panel.

Press "Exclude folders" and make sure there are no paths to archive in the list. If present, click on the folder name and press "Remove".

To exclude other folders, click on "Add" and select the directories to avoid.

Click on "Save changes", then on "Advanced settings" and set the time interval between one save and another.

Choose to delete previous versions of files based on a time interval or disk space availability.

Press "OK" to activate File History and start the first data copy.

Note: if the disk is not recognized, format it manually in exFAT or NTFS.

VERIFICATION AND TROUBLESHOOTING: How to test if it works and what to do if it fails

After cloning the disk, it is essential to verify that the operation was successful and know how to intervene in case of problems.

Verification of the cloned disk

• Visual check: Verify that all partitions are present on the destination disk.
• System boot: If you have cloned the disk with the operating system, try to start the computer using the cloned disk.
• Data comparison: Open some files and folders both on the original disk and on the cloned one to ensure that the data is identical.

Troubleshooting

• Disk not recognized: If the destination disk is not recognized, make sure it is correctly connected and formatted in exFAT or NTFS.
• Error during cloning: If the cloning process fails, check that there is enough space on the destination disk and repeat the operation.
• Boot problems: If the operating system does not start correctly from the cloned disk, check the BIOS/UEFI settings to ensure that the disk is set as the first boot device.
