Random extra hard drive after windows update.

Last night I had to update Windows. This morning I started up my pc, had to look at what new stuff came with the update and randomly got a notification that my local disk (F:) was full.
Ofcourse I checked "My PC" and to my surprise I found a new hard drive that used up 88% of its capacity.

I only own 1 HDD and an SSD where I have windows installed on. (There are no other drives besides these 2 in my pc)
I am not sure what caused this random drive to pop up, if it is harmful, or how to get rid of it again.

All I know is that I get the notification every 5 minutes and it is getting quite annoying.

I hope someone has an answer to this.
