NAS on Aiport Extreme constantly spinning up
I have a 5th gen airport extreme with a 2TB NAS drive in the USB port. I use this HDD as a time machine backup, and to hold various other items I dont want on my Computer hard drive.
The problem is it CONSTANTLY spins up the NAS drive. Sometimes its once every 5 minutes, sometimes 2 or 3 times in a minute. I am not transferring anything to/from the drive during this. It backs up as time machine every hour on the dot, and hasnt missed a backup in months. When it is not backing up, it just ocnstantly spins the drive up. Over and over and over again.
Any ides as to what may be causing this?
Thanks.
