You don't have to use nvidia's drivers with your nforce motherboard if you aren't using RAID or don't need hotswap. The microsoft drivers work just fine and do not cause these errors. To remove the nforce sata drivers (under Win XP) go to device manager and select IDE ATA/ATAPI controllers, select the nvidia driver and select properties. Under the Driver tab select Roll Back Driver. Reboot and that should load the microsoft drivers and you won't get these errors. If there are previous versions of the nforce sata driver that get loaded you can uninstall them in add/remove programs.
