What's my hard drive's model number?

How to find your device’s model number

To identify the model of an external hard drive, you’ll need to open the enclosure, extract the drive itself, and then check the label on the actual hard drive.

There are a lot of numbers on a drive’s label, but which is the actual “model number?” See the example hard drive labels below to identify your hard drive’s model number.

Select the manufacturer on your hard drive’s label:

Seagate

Seagate model numbers start with “ST” and are often found in the top right corner or left side of the label, near the “firmware version” and “part number.”
