Note that I have two different power cables attached, one to each pair of drives, and I am getting the messages on different drives from time to time, not nearly every time. I would say it's happening approximately 15% of the time, and always only occurring on one drive at a time despite having two drives per power cable. Given that, it seems unlikely to me to be a cable problem. Do my symptoms indicate a possibly faulty SATA controller? The system is fairly new (last 1 1/2 months). It is dual boot but I don't use 2 of the drives in Windows. That being said, on the other two drives I haven't noticed the problem occurring there. So, I am wondering if it is a linux-specific problem, perhaps with the ahci driver.
