Sorry, all I can do is provide the documentation that it works and I'm not nuts!Bookworm, you may be the only one to have success with your 8TB (in total) disks. Did you check on your firmware?[
Picture of the size of disk 1: 6TB drive right off the screen (6TB in a disk enclosure - Amazon link also included
Picture of the size of disk 2: TB drive right off the screen (old WD 2TB MyBook)
Picture of Firmware version - still U927
Picture of the actual devices and how they are connected
(USB out is the blue cable on the far right
(Left hand USB port is the 2TB Drive)
(Far right USB port is the 6TB Drive)
So you look and, if my math is right, you can see that they total up to 8TB of space. It's only addition!
It could be the enclosure? It could be the cheap hub? Who know? Either way, I have 8tb of space!
