If you have a Windows 10 computer, you can find the serial number of your hard drive by using the Windows 10 system utility called “Windows Update”. To do this, open the Windows 10 system utility and type “windows update” into the search bar. Then click on the “Update my computer” button. You will then be taken to a page where you can find your hard drive’s serial number. You will need to enter this information into the text field at the top of the page. Once you have entered your hard drive’s serial number, you will be able to update your computer by clicking on the “Update my computer” button.


If you’d like to know your hard drive’s serial number for warranty or other purposes, there are a couple of ways to check this number in Windows 10. We’ll show you both graphical and command-line methods to do this.

Know that both methods outlined below work for multiple drives, too, in case you use more than one hard drive with your PC.

The Easy Way: Use a Graphical Method

We recommend using Seagate’s free Drive Detect tool to check your hard drive’s serial number graphically. With this tool, you can quickly check the serial number for any number of hard drives attached to your PC.

Although the tool is made by Seagate, it works for non-Seagate drives, too.

To reveal your hard drive’s serial number with this method, first, open Seagate’s Software Downloads web page in a web browser on your PC.

On the web page, scroll down to the “Utilities and Plugins” section and click “Drive Detect.” This will download the Drive Detect tool to your PC.

Once Drive Detect is downloaded, double-click it to open it. This is a portable tool, so you don’t have to install it to use it.

In the Drive Detect window that opens, you’ll see all your hard drives listed. Next to each hard drive, you’ll see the drive’s serial number. This is the number that the manufacturer has assigned to the drive.

That’s a quick and easy way to read your hard drive’s serial number!

The Geeky Way: Use Command Prompt

If you don’t want to use a third-party app, or if you prefer command-line methods, you can use a command with Command Prompt to reveal your hard drive’s serial number.

This method shows the exact same serial number as the method above.

To start, open the “Start” menu, search for “Command Prompt,” and click it in the search results.

In the Command Prompt window, type the following command and press Enter. Feel free to copy the command from here and paste it into your Command Prompt window.

After entering the command and pressing Enter, Command Prompt will display a list of all your installed hard drives. In the “SerialNumber” column next to your hard drive, you’ll find the drive’s serial number.

And that’s how you find your drive’s serial number without taking it out of your PC! Very handy!

Want to find your PC’s serial number? It’s equally easy to find that.
