Your BIOS does not support HDDs over 127GB. Try to get a BIOS update for your motherboard (or IDE controller if you are using one on a card, but this is highly unlikely). Failing that, get drive overlay software such as OnTrack, or a modified version of OnTrack from your HDD vendor, i.e. MaxBlast for Maxtor drives. Usually, HDDs come with a CD or floppy in the package that has drive overlay and formatting software included, but this isn’t 100%.
