Hi just as a added note. There are no hard drive drivers but there is a controller that makes the hard drive work . It is the sata controller there are a few different ones and a version of windows may not have yours. In xp you would start the install and when asked if you have any third party drives to install push f6 you would do that and have those sata drivers on a A disk, or if the os and the pc supports it on a usb stick ie win 7 would support usb. In win 7 there is a part in the setup at the start you get a window and click a button if you have sata drivers to install. The way to get the sata drivers is from your mother board manufacture’s web site. Make sure that the hard drive is listed in bios as a first setp.
