Don't take this as advice as I have never done it; however if I were in your shoes, I would take out one of the disks that isn't playing nicely and rebuild the array. Once it is running smooth then I would take the other disk that isn't playing nice and replace it and rebuild again. The whole process will take a fair bit of time but better to be safe than sorry. Like I said I have never done it so do so at your own risk.
