We have a Win 2003 Server with 2 SATA drives. I have a 750 gig SATA drive that I want to install in it. This drive was satisfactorily formatted (NTFS) on another machine. But the server won't recognize it, in spite of their being 3 unused SATA ports on the motherboard. I've tried different ports and cables, but the 3rd drive won't show up anywhere, not even in Disk Management. Any ideas, please?
