Complete Drive Test Failed

I have owned my passport Essential for well over 2years of now, havent used it much to be honest.

I was running through Wd smartware software Diagnostics where i found that my disk failed the Complete drive test.

Althought it passed the SMART test, now i m not sure what failing the Compete Test exactly means. If anyone here could help me how to fix that ill be very grateful 

Hello,
