Can you see what the SMART event was?
I would be surprised if it was a driver issue. PROBABLY one drive is having issues, and needs to be returned. I'd consider running just 1 drive by itself for a while, see if it's good (and back up important stuff frequently). If it runs OK, try the other independently, and see what happens.
Thanks for the info. The only thing I can find on the event is that the data may be at risk.
I felt in there one time it was making the clicking noise and it felt like both drives were making it. I will try to remove one and see if the remaining one makes the sounds etc. thanks
