MyBook 2TB Event Viewer ID 51 - Error detected on device

I’m having issues with my external drive where at times, I cannot see/access the directory path.  When I go to windows explorer, I see the drive letter but when I click on it I cannot see the directory structure beneath it.  I’m forced to reboot the pc.  I noticed numerous occurrences of the following error message in the Event Viewer:  

An error was detected on device \Device\Harddisk1\D during a paging operation

I also periodically receive a windows write error messages indicating a write failure to the $MFT, data is lost (on external drive).  Any ideas as to what’s causing this or how to resolve?

Hello, if possible you can try connecting the My Book to another PC to verify if the same problem happens again. You can also run a test with DLG. Check the link below for the steps.
