The drive had failed from the Virtual Disk. If the controller and everything is out of date causing timeouts, then the drive may not have failed due to a hardware fault in itself, but instead may have been caused by a communication failure. If we update the server and then successfully rebuild the drive then we know the drive itself wasn't the issue.
