hi everyone, ive added a new harddrive to a dimension 2400. the hard drive is supposed to be 120gb but its only showing up at 31.4 (yeah weird number) is there anything i could try to get it to read the whole 120gb. ive tried reformating and checking the disk. also the harddrive is from an hp comp if that makes a difference but its been reformatted and everything so yeah.

thanks
