My NAS began blinking out an apparent Error code (red light). It is 5-long followed by 4 -short. That translates to 5x10 + 4x1 or 54 if I remember their scheme correctly. But I don't know what error that refers to. My manual doesn't go into that part. The NAS still functions as normal, but this may be an indication of impending failure. Is there anyone that can identify this error? I'm stuck.
