Hi and Welcome. My Name is ***** ***** I look forward to assisting you today with your question
No, you don't need any drivers or software. These are plug and play devices. Are you sure the drive is working ? Connect the hard drive to your computer with the USB cable (connect it to different USB port this time).
Then go to Applications > Utilities folder and open Disk Utility. Do you see the hard drive in Disk Utility ?
I'm sorry, that means the drive has failed. Did you test it on different computer ? This will tell us if there is any issue with your Mac
