Server 2012R2 - Drives using mountpoints - display warnings in Device Manager

[SonicMojo]

As I move towards completing a new home server build with Windows Server 2012 R2 - I was checking Device Man today and noticed an odd pair of yellow flags in Device Manager.

 

In the attached graphic - you can see the flags - associated with two Seagate 4TB NAS drives that I have installed.

 

In order to clear the clutter of drive letters (This server uses Stablebit Drivepool to display a single large drive) - I am using mount points for the drives.

 

Upon further inspection - I see Error 10 saying this device cannot start. But all the actual drives are fine and online - taking data normally.

 

What do we think the problem is here - am I missing a driver or inf file or something?

 

Ideas?
