I just connected a slave hd to my new motherboard (last motherboard had same problem but I thought it was the mb then, but now as this one has same problem I know it isnt) Master is a 80gb hd with windows etc.. and this new 200gb says its only 31.4gb. Ive tried the maxtor software for "true size tdetection" but didnt work.. So I thought u guys could help. Formatting drive didnt help. Its NTFS.
