You don’t need to disassemble your laptop only to check the specs of your HDD. If you want to check the serial number of HDD installed on your computer, you can use utilities like
wmic. What about the HDD model?
Windows 10 and other modern desktop operating systems have a default utility to allow you to check the specifications of your HDD. In Windows 10, the utility is System Information which you can access via the start menu. Not only System Information displays the specs of your HDD, but also other components including sound card, graphic card, optical drive and so on.
To open System Information, click the start menu of Windows 10. System Information lies under the Windows Administration Tools folder.
Or, you can also type
msinfo32 on the Run dialog (Read: 118 Run Commands You Can Execute on Windows 10),
Once the System Information window opens, click Disks on the left panel. You can find it under Components/Storage. On the right panel, you can see the detail specs of the HDD installed on your computer, including the model.
As you can see in the screenshot above, the HDD model is ST500LT012-1DG142, which is a Seagate hard drive designed for laptop. This HDD model has the RPM of 5400 (detail documentations).
In addition to the HDD model, other key information displayed by System Information regarding your HDD includes the number of partitions, the number of cylinders, the number of sectors, and storage capacity (size).
Another way to check the HDD model on your Windows 10 is via Device Manager, which you can access via Control Panel. Click the start menu and select Control Panel, which lies under the Windows System folder.
On the Control Panel window, click Hardware and Sound followed by Device Manager.
On the Device Manager window, open the Disk drives by double-clicking it to see the list of the installed drives on your computer. You can directly see the HDD model on the list.
Double-click an item on the list to see the detail information about it. By the way, you can also type
devmgmt.msc on the Run dialog to open Device Manager without performing too many clicks. Press the Windows+R keys to open Run dialog.
