Hello, I just purchased a Samsung 250GM SATA Hard Disk, 3.0Gb/s with a jumper setting allowing for 1.5Gb/s data transfer. My motherboard supports 1.5Gb/s SATA. So, I just set the jumper properly, connected the hard-disk and everything works fine at the beginning. The system recognizes the name, size and everything but then it suddenly freezes. I attached photos of the screen where it freezes on. The motherboard is Asus P5GD2. Please let me know if you require further information, and thanks a lot in advance, for any help. EDIT: Screens are attached now...
