Not a problem .. voltage surge protection is available and can also be used for black boxes.
I suggest you install one .. or you will lost another hard disk if another voltage surge
If the voltage surge is the result of lightning ... the protection will be useless ...
It's kinda too late now
but fortunately I had data backups. Actually the replacement power supply (replaced on warranty) also failed after a couple of years, but this time in a benign mode. Maybe they had learned something at the manufacturer...
Anyway my point was that also independent power supplies do sometimes fail.
