I'm not sure if this is the right subforum to post this, but I haven't found anything about this exact problem anywhere else on the forum, so if I put this in the wrong place, please move it! That being said...
I picked up the DIR-866L on sale last weekend and got a Western Digital My Passport Ultra 1TB USB drive to serve as a cloud drive for my personal network. It took some tinkering and tweaking, but with some trial and error I finally got everything connected properly and installed. I have SharePort Plus on my Windows 7 desktop and MyDLink Shareport on my Galaxy Tab A and iPhone. Everything works fine except for one thing...
...the My Passport drive won't spin down or go to sleep when it's connected to the DIR-866L, no matter how long I wait. Ever since I moved about 100GB worth of files onto the drive over the weekend, the drive keeps on spinning and spinning and spinning and won't go into sleep mode at all. The drive light keeps blinking rapidly most of the time (though right now it's a solid blue light though still spinning). I have no idea what to do or whether this is actually normal behavior. Can anyone help?
