I bought an Asus H87M-E. I can't install 3 X 3TB hard drive Raid 5 on this board. It is a new board, I can't find Bois update. I created the Raid5. the O/S displays the drives with different sizes 2048, 745, 1875GB. I have no idea what is happening! Tech support said it is windows problem, But I don't buy that. I broke the raid and try to install the O/S on a single drives, but the O/S recognize it as 745GB.
