The initial sense information gives a code of 0x0/0x0, which literally means 'no additional sense information'. Afterwards, the drive complains about the bus resets that the card initiated. So, there really isn't any useful information here. It's possible that the drive is going bad, or that you are having problems with cables or connectors, but it's hard to say. Probably the easiest thing to do would be to try swapping the drive out.
