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

by "cannot access" do you mean that the file manager doesn't list it? how have you tried to access that has not worked?

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.

What does df -h report?

For example:

Code:

charlie@charlie-machine:~$ df -h
