Error code 52 , WIN 7

It’s a 3TB disk ,



The problem is  :

Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)

What can I do with this , the files inside are important
