Please give details about your entire hard disk layout - it sounds like you've got GRUB and Win32 living on one hard disk and SuSE 9 living on another hard disk, and after you added a third hard disk you fUx0r3d the boot loader and can't boot SuSE anymore. The most likely thing is that GRUB is looking in the wrong place.
