Unfortunately, your WD Elements may be showing signs of degradation. I would suggest a full S.M.A.R.T. and sector diagnostic test on your unit in order to confirm the actual health status, as explained in the following link:


In case the unit unfortunately fails the tests and is still under warranty, the best course of action would be to replace your product with us Western Digitalby creating a Return Material Authorization (RMA) for free:
