Why do you upgrade to a larger disk?

  • Have you ever encountered the problem of running out of free disk space? You must feel desperate when this happens because you are unlikely to upgrade the system, applications or simply save the new data. For this, you should upgrade to a newer and larger disk and then install all applications or upgrade an operating system without worrying about the insufficient disk space. But reinstalling all applications and operating system is time-consuming job. How to solve this?
  • Windows will alert you by popping out a Windows low disk alert if your computer suffers this kind of problem. It says: "You are running out of disk space on Local Disk [drive]. To free space on this drive by deleting old or unnecessary files, click here." or some other kinds of disk space warning.

How to solve disk low space?

To solve this problem, we would like to share three useful ways of increasing disk space:

One. Remove some programs that have installed in your computer.

Two. Extend partition by shrink other partitions and extend partitions which are too small.

Three. Upgrade the hard disk to larger one through disk clone and transfer all the data from the old disk to the new one.

How to upgrade to a larger disk?

Here we would like to introduce an effective way to upgrade a disk without taking time to reinstall the operating system or applications. That is to upgrade disk through EaseUS Disk Copy, a specialized disk copy/clone tool recommended by worldwide users.

Firstly, please connect both of your drives to your computer where EaseUS Disk Copy is installed and then follow the direction to upgrade the disk by cloning the entire disk to a larger one without reinstalling operating system and applications.

Prior Notice:

  • The "Sector by sector copy" asks the size of your destination disk to be at least equal to or larger than that of the source disk. Leave this feature unchecked if you wish to clone a larger hard disk to a smaller hard disk.
  • All data on the destination disk will be completely erased, so take care.

Step 1. To start copying/cloning an entire disk to another, choose this disk as the source disk under "Disk Mode" and click "Next".

  • "Autofit the disk" makes some changes by default on the destination disk layout so that it can work at its best status.
  • "Copy as the source"does not change anything on destination disk and the layout is the same as source disk.
  • "Edit disk layout" allows you to manually resize/move partition layout on this destination disk.

Tick the "Check the option if the target is SSD" option to put your SSD in its best performance.

Step 4. Click "Proceed" to officially execute the task.

After all these steps, you will successfully upgrade the hard disk to a larger one and transfer all the data & system on your original disk to a larger one in a very easy and safe way.
