Case: Clone Laptop Hard Disk to External Drive
I purchased an external SSD drive and I am trying to clone my laptop hard drive to the external drive, and remove all the content from the laptop hard drive. How can I do that?
Data stored on a laptop is not always safe. In addition to system failures and malfunctions, hard drive corruption is one of the common reasons for the loss of important files. Therefore, you may want to copy the contents of laptop hard drive as a backup, or replace laptop hard drive without losing data.
In either case, cloning laptop to an external hard drive is an effective solution.
Speaking of copying hard drive, you might think about manual copy & paste first. Does it really work?
Generally you can duplicate most of the data with copy & paste in File Explorer, but boot files, protected files and hidden files are not included. It won’t help you transfer OS to another hard drive, and the transmission speed is also not suitable for enormous data.
The easiest and safest way to clone a laptop hard drive along with OS is using disk cloning software. It will greatly speed up the process and simplify the operation. Also, the cloned hard drive is bootable - you don’t need to reinstall Windows 11/10/8/7 from scratch.
