Why should you clone hard drive in Windows 7?

Cloning a hard drive means to make an exact copy the drive including installed operating system (OS) and other contents. Actually, cloning Windows 7 hard drive serves a lot of purposes, and it is not hard. This article will break it down step by step.

Insufficient disk space, upgrade to a large one

Everyone knows that the space of a hard disk in Windows 7 is unchangeable, but the stored data on it may increase day by day. Therefore with time goes by, your Windows 7 may be in low disk space.

If this problem can’t be solved as soon as possible, your system might crash when free space in Windows 7 hard disk is extremely slow. If you do not want to delete much stuff saved on your computer, you can upgrade your Windows 7 hard drive with a large one without reinstalling Windows or installed programs.

Low performance, upgrade to a solid-state drive (SSD)

With high demands for fast speed, most of the users will choose to upgrade the present hard drive to SSD. Actually, it is considered as the best upgrade for old PCs that can be easily achieved. Unlike any other parts of the computer hardware, hard drive is easy to take out and replace.

In case of system issues, clone hard drive as a backup

There are many factors that can cause system problems, like ransomware, virus, and accidental deletion of crucial files. Moreover, any hard disk drive (HDD) or SSD has a limited lifespan. It will eventually wear out, so it is recommended to clone the hard drive as a backup to protect your data.

Install system by cloning the hard drive

Some companies or organizations may need a lot of computers with identical hardware and system configurations. If that is your case, you can install and configure one computer, clone to multiple hard drives and then install the cloned hard drive to all the computers.

What should you prepare?

1. A working computer and the hard drive needs cloning.

2. A new hard drive or SSD. It does not need to be larger than the original one, but it should be enough to hold all the data saved in the current hard drive.

3. Cables or adapter to connect the new HDD or SSD. For a desktop, you need a power cable and data cable to connect the new drive in your computer as a secondary drive. For a laptop, you need an SATA-to-USB adapter to connect the new drive externally.


Some laptops have a second drive bay or SSD slot that can also be used to connect your destination disk. You can also connect the other drive via an adapter in your desktop and then install the cloned drive on your computer.

If you do not have the device to connect your new drive, there is a workaround to clone hard drive with USB cable.

4. A hard drive cloning software for Windows.
