So I have a 2015 shield TV, fully up to date. I have an external HDD attached via usb (not adopted), that has a sleep setting baked in for 30 minutes.

The problem is something keeps accessing the external HDD randomly. Even when I have revoked ALL app permissions, including system apps it accesses it randomly like every hour.

Does anyone else have this issue and have you been able to fix it? It's really irritating.
