ok i have 2 hard drives, both maxtors, and my C drive, is fine, cause its at UDMAmode-4 (ata/66), but my D drive maxtor only runs at UDMAmode-2(ata/33), but i know my d drive supports mode-4 because they're almost the exact same hard drive, but one has like only 6 more mb of space then eachother... so can anyone help me? :sleeping: oh yeah i forgot to mention at the startup of my computer, it reads them both as UltraDMA Mode-4 status OK
