Usb Connected Hdd Could Not Mount

[bumperbee]

Hi Birdman, very sorry for the wrong info, it is Mount Manager.
As requested, I open the \proc\partitions file and it appears empty. The sizes show 0Kb and there is nothing in it.
It seem I am able to attached an image now, pleased see image that show both my internal 3Tb & Usb 5Tb Hdd is mounted. But the 5Tb Hdd capacity is read as 2.86Tb which is incorrect and it’s the same capacity with the 3Tb Hdd.
