Posted in Tricks   LAST UPDATED: JULY 31, 2021

Most Windows and Mac users don’t know that as their device gets old or runs out of disk space they can very easily change the hard drive to a bigger one. Most of you must be aware of this but are having trouble figuring out how to execute the disk cloning operation on your own without losing any data and OS.

Here we will show you how.

When Do You Need to Clone a Hard Drive

So when do you start considering cloning a hard drive to a new one? There might be numerous occasions when you might need to clone your hard drive

  1. If the old disk runs out of space - Upgrade your hard drive to larger hard disk

  2. If the computer gets old and slow - Upgrade your hard drive to a newer disk

  3. When transferring the whole contents of your hard drive

  4. The OS can’t be migrated by copying and pasting Windows files to a new hard drive

  5. For protecting data from virus or malware infection - Create a full backup of disk data

So how do you clone or upgrade the hard drive successfully and safely? The following instructions will show you how.

Preparing for Cloning Hard Drive

Before you start to actually clone your hard disk, some preparation has to be made.

1. Hard Drive should be made ready

  1. You have to get a second drive with sufficient capacity. To make the disk cloning process smooth, the second drive must be made equal to or even of a bigger capacity than your present hard drive.

  2. The new drive needs to be connected to the PC. If there’s only one disk slot in your computer, connect properly to your PC by a SATA-to-USB connection cable. If your computer happens to have a second slot, install the new drive to your PC.

  3. Initialize the new HDD/SSD. When cloning and upgrading the hard drive in a Windows PC, make sure that you initialize the new drive in Disk Management.

2. A Reliable Hard Drive Cloning Software should be downloaded

Because the tools for cloning disks on Windows and Mac computers are different, the right disk cloning software should also be downloaded and installed keeping in mind your operating system.

Cloning a Hard Drive on Windows

This applies to Clone hard drive to HDD/SSD in Windows 10/8/7/XP, and even Windows Server machines.

c) Creating a Portable Windows USB drive - This option makes sure that the cloned USB system disk is able to boot normally.
