As you may know, hard drive clone is the course of copying all contents from one hard drive to another via cloning software or hardware. Usually we use it to upgrade current hard drive or do a disk backup. Maybe you would ask how to clone a hard drive in Windows or Mac. Luckily! Two simple and practical solutions will be shown below.
Preparations before cloning hard disk
Can’t wait to know the operation steps? Don’t hurry! Some preparations need to be done before cloning.
Connect the target drive to your computer. Make sure that it has enough space and can be detected by the computer.
Don’t forget to prepare a screwdriver if you are a laptop user. After cloning, the screwdriver can be used to replace the old hard drive.
All data on the new drive will be deleted during the cloning process. If you have some important data on the new hard drive, you’d better do a disk backup in advance.
Prepare a reliable cloning utility. If you don’t have such a program, please refer to the next section.
