I did a search and I am seeing a lot of people who claim that the 5S5A firmware has caused trouble. I have thge same drive that you have and have not had any trouble with the firmware it shipped with so I never flashed mine. I figure that as long as it works I wont mess with it. You could try the new firmware if you want, and flash back if you have trouble I guess, but I always feel like I am taking a chance of messing up a good drive. Anyone have anything good to say about this firmware?
