A lot more than just 5 sectors. I'd replace the drive and the cable. If it's under warranty, have it replaced. If not, maybe ata secure erase it, extended offline smart test, and use it down the road for something not so important if it passes without further problems. So basically, replace the dead sda drive ASAP so it can start rebuilding. I'd consider marking sde faulty so that it's neither being reshaped or rebuilt and then replace it once the new sda is rebuilt. You can probably replace them both at the same time and have them both rebuilding; but I'm being a little conservative on how many changes you make until you get yourself back to some level of redundancy.
