Just bought a 500GB SATA2 hdd, but it's not working. When plugged in it stops my other 200GB SATA drive working. Motherboard is K7Upgrade-880. This motherboard does not say that it supports SATA2, but one assumes that it is backwards compatible. Do I need to update the firmware/software for the SATA Controller, or am i going to have to get a new board....
