Comment 5 for bug 159521

In case it helps, I checked the SMART status of the drives too. Only the drive associated with ata1 has errors in its SMART error log. However, the drive is reporting as healthy, and running a long selftest produced no errors, and no change in the "healthy" state of the drive according to SMART. I dont know enough about this to understand if the errors in the log are causing the problems I'm seeing, or as a result of them. I've attached the output from running "sudo smartctl --all" for each of the drives to this post in the hope it will be of use.
