Keeping External awake

I just purchased an External 3 TB Element usb 3.0. I use it for my movies and music on my plex server. Problem is that the Hard Drive goes to sleep when the computer does and My Plex server cannot find it. Is there a way to keep the HardDrive awake while the computer is on even when the computer is asleep?

Not sure if that’s possible. Unfortunately, the drive will respond to the computer settings.

The WD Elements is a plug and play drive and if the computer goes to sleep, it will do the same.  Unless someone has an application that keeps the drive awake.
