Need help finding your hard drive’s model number?

If you have an “external hard drive,” and the “bare drive” is still inside the enclosure, you need to disassemble the enclosure first and then remove the hard drive. Only then can you find the model on the hard drive’s label.


There are a lot of numbers on a hard 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 | Maxtor | Western Digital | Fujitsu | Hitachi/HGST | Toshiba | Samsung


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.”

Still can’t find your Seagate model number? Try Seagate’s free online Model Number Locator (scroll to the photos at the bottom of the page; DO NOT install the software since your drive needs to remain powered off).
