I think atm you have to assume that drive has failed and needs replacing. If you have a suitable spare then begin the replacement process asap. If not then get one ordered asap. Make a note of its physical location so that if your replacement drives suffers the same issue then you will need to carry out further investigation into that slot to see if there is any cable issues.
