Missed that you use DrivePool. I found it more suitable to add to the config a path to the PoolPart folders instead of the mount points. Like this: disk d1 \\?\Volume{310e5519-a8bb-4f9c-adc6-1bfc41faa215}\PoolPart.a7afc26a-60e8-4ee7-8224-35d012e8718d\

Just change some drive's letter to its mount point in the config and try diff (it's read-only).

I also faced this problem and even created a separate topic, did not know that this thread is already there.
