Any advice as to what I could do to test the drive/setup is appreciated. Please be aware I'm no linux guru, my field is in something completely different and I just happen to love learning about linux and have found it very useful to complement my office setup and work.
I had a bit of a look at dmesg, I didn't google all the errors however to me it looks like you possibly have a bad cable or SATA port. You could try swapping the SATA cables and ports (although, don't do it if the RAID isn't rebuilt!) and see if the error follows the drive, cable or SATA port.
There is also some suggestion it might be the mode the hardware is running in or some kind of power management problem.
