WD 1TB (Black) Passport External Drive Scan Now Error

Problem is when i connect my drive to my PC or Laptop, my drive not showing in My Computer, but when i open disk management and assingn new letter to my Passport Drive, problem solved. The other problem is that when i check now my drive for errors in properties, the pop-up window appears with a message that “Wndows was unable to complete the disk check”. Good news is that my drive passed the quick test in WD Data Lifeguard Diagnostic Test.
