RT-AC68R EXT4-FS Error Logs? Drive won't wake up.

[ezflrouting]

Running Merlin 3.0.0.4.374.39. Have a USB 3.0 WD My PassPort drive connected to the USB 3.0 port.

After so many hours (a day?), the router believes that the HD is asleep, and it can no longer be accessed from other devices on the network. Furthermore, the Network Map shows no HD connected, and the USB 3.0 light on the front of the router is no longer illuminated.

If I reboot the router, it appears again and functions.

I've updated the WD HD to its most recent firmware and also ran the WD Drive Utility to "disable" sleep mode.

In the router:

Wireless->Advanced->Reducing USB 3.0 interference is Disabled.
Tools->Other Settings->Disk Spindown = 0
....Exclude the following drives from spinning down [all unchecked]
...........I've even tried the "exclude spindown" with all three drives checked.

Here are some logs from the router, I am guessing that this is when the error occurs.

Any ideas?
