Depending on what the cause is there isn't really anything that can be done to fix it on the Ubuntu side. The controller I noted I saw the problem on was the controller's fault. It was writing data to the drive even when not in RAID mode with no regard to what the OS wanted to do with the drive. That is a bug in the controller firmware not Ubuntu.
