Note: When a task is in progress and the system is shut down, the RAID driver may hang under cer- tain circumstances. This may occur if arrays exist and a task is in progress, but a drive letter has not been assigned AND an OS partition has not been created on the array. Because neither a drive letter nor partition has been assigned, the OS doesn’t notify the RAID driver that the system is shutting down. If this condition occurs, the sys- tem can be reset, the OS will start, and the RAID process will also restart.
