We found that both of our K3 servers occasionally would eject a disk from the RAID0 array because it lost connection briefly (which results in it being marked as Unconfigured Bad in the manager and no longer presenting the array to Windows as a valid drive).
If the drive hasn't actually failed and was only momentarily lost then data on it may be recoverable, but you only get one chance to fix it correctly.</div>
