David upgraded to Windows 8, but he's lost his firewire connection as a result. Leo says that upgrading an old PC to Windows 8 usually isn't recommended, but it sounds like David needs to get a firewire driver from the motherboard manufacturer. There's no indication that Windows 8 doesn't support it. He just would need the driver. Leo also says that doing a clean install wiped out all the older drivers, this is one case where an upgrade may have been the better move.
