This one above indicates that you drive is developing bad sectors. All
drives come with 'spare' sectors that can be remapped to the usable
space if ine or more becomes bad. Your drive has reallocated 35 bad
sectors and is most likely out of spares. Regardless the drive is
failing and must be replaced. In addition to that the data that was
stored on those 35 previously bad sectors is most likely irretrievably
lost. I hope that your raid setup has saved you from this data
corruption.

Your disc has been steadily failing for the last ~1800 hours.
Buy a replacement and swap it out asap.
