My NAS PR4100 have notified me that 1 drive is not working properly
I have raid system - spanning
Enclosure 2 has a solid red light
I bought another NAS same capacity WD RED
shut my system down and changed the troublesome disc. Powered up and have 4 solid red lights showing
Do I format the new drive before adding to my system and click rebuild in setting menu?
Any information gratefully received thank you
