One of the hard drives of my “My Book Live Duo” is in failed status. I am using it “Raid 1” mode. The attached hard drives are “Hitachi HDS5C404” (4 TB).
I want to replace failed hard drive with healty one. Is WD Red (WD40EFRX) 4TB compatible with my MBLD or not?
Should I replace both hard drives or only failed drive?
