What is the hard disk serial number and how to check it?

A hard disk will be assigned with a new disk serial number whenever you format a hard drive. This serial number is used by software programs installed on the computer to identify the disk driver and prevent multiple activations of the same software on other computers.

You can do a quick check for the serial number and other basic information on your hard disk:

Step 1. Open the Start menu and search for Command Prompt.

Step 2. Launch Command Prompt and type the following command and press Enter:

wmic diskdrive get model,serialnumber

Once you complete the steps, the command will return the manufacturer, model, serial number, and size (bytes), including removable drives.
