Emby preventing HDD from going to sleep?

[Ponyo 22]

I was wondering, how often is Emby accessing/scanning the hdd the media library is on?

 

I got all my media on a external usb drive and I would like the drive to turn off so it doesn't make any noise when not active (I'm a light sleeper) but it seems something is preventing the disk from going to sleep. Since I only got Emby and Kodi installed I think its Emby.

 

Not surprising if its Emby that is preventing the disk from going to sleep but just want to confirm it.
