Hey there, DayVideo!
I'm sorry to hear about your external WD drive.
🙁 Even though it was given to you, you should still check the warranty of the drive on our website here:

The buzzing sound might be an indication of internal/physical damage on it and, unfortunately, this is something you won't be able to fix by yourself.
If you need further assistance or any questions answered concerning the WD drive, I'd recommend you to get in touch with our technical support:

Hope I was helpful! Best of luck!
