Check the manufacturers website for any software downloads and whilst there, see if there are any FAQs. With a drive, be it internal or external - if you can't trust it above 99.99% then it is a paperweight and nothing more.
Also, have a swap around with the USB ports. Unplug and replug it to see whether it is correctly identified by your system. See what the device manager makes of your little bargain.
Hope it all checks out.
