i think its fine. i'll check the way mine registers when i get home as i have the same motherboard and the 8mb cache model of that drive. i'm pretty sure its just a trick the NF4 chipset uses for compatability though. thats why (to my knowledge) you shouldn't need SATA drivers for a hdd connected to the nVIDIA controller on an NF4 motherboard
hmmmm :/ mine says SATA. i think its still like i said though. probably because my boot drive is actually ATA133. if my thinking about it being for compatability is correct it would only be necessary for the boot drive.
