You omitted one critical piece of information. What kind of drive is it? This is likely a drive firmware problem. This commonly happens with Quantum Atlas I and II drives, and can generally be fixed by upgrading the firmware. It's also possible, of course, for it to happen on other types of drives as well. What the "timed out while idle" message means is that a command from the da driver timed out, and there was nothing else going on at the time. This generally means the drive has gone "out to lunch" and hasn't come back. The timeout for the da driver is 60 seconds, so it's highly unlikely that your drive just wasn't able to respond in time.
