In my experience, problems like this are often casued by broken/unreliable cables / connectors / backplanes. As a first measure, try replugging the SATA cables. If this doesn't help, try swapping arount the disks and cables to see if the problem is with the cable (sticks with the disk) or with the backplance (sticks with a physical port). Then replace the faulty components.
