use command prompt (admin)

use the disk part command to wipe the partition tables off the drives.


like so.

> diskpart

List disk

sel disk #

clean

in that order. Then open disk management (this is easier than doing it via cmd)

make sure the drive is initilized as GPT (mbr has 2TB limit)

it could also be the sas controller. some only support certain size limits, but if one shows correctly im willing to bet its the init type.
