If it's f.i. your BIAB audiophile drive, type WD My Passport USB 3.0, you might still have warranty. I found them very reliable sofar. You could run a checkdisk routine from Windows, and mark 'fix bad sectors' doing that. Takes some time, but might repair your drive.
Important: Usually USB drives themselves are not the cause, but misuse. You cannot unplug them un-punished, with out using a proper eject routine from within windows.
For copying files i'd prefer FastCopy (freeware) or Teracopy, has some verifying options. -F
