Ok, this is much clearer. You have a kernel or hardware problem, it doesn't see the connection of the USB at all. [See below]
Can you try with another operating system in the same computer, same cables and disks? If you don't have any installed, try booting from live media. First an openSUSE live, then some other distribution.
I now installed one more hard drive, and detached the others. Then I installed the Kubuntu operating system. The result was the same: No contact with the disks. The strange thing is that there is no problem whatsoever when attaching USB sticks to the same cable and the same USB port. Per Inge Oestmoen, Norway ----
Then I attach the external disk, and here is the result *after* it was attached:
