Red face Ubuntu cannot access my 4TB external hard disk


It can access the USB storage with no problem and another external generic 2TB HD

I even purchased a new USB 3.0 cable but the result did not change.

I am running TestDisk 7.1 and this is the output so far

When I plug it in while my Ubuntu is running it does not recognize the 4TB HD. It recognizes my 2TB HD and USB storage sticks without any problems.
