I purchased two 6TB Western Digital Black hard drives. WD6001FZWX. Both brand new from Amazon. When I put the first in my 4 Bay Gen 3, it reported the drive as a bad disk. I also tried the first drive in my Drobo 5N with the same result.
I also tried a USB-SATA cable and never felt the drive spin up. Tried the second drive in the Gen 3 with the same results.
Did I just get two bad drives or is there something special needed to get the bigger drive working in Drobo.
