Have a look in the device manager and see if it shows any conflicts, another thing to try is disabling ALL running programs by your clock by right clicking on each in turn and select exit\close etc wherever you can, then tell the system to scan for hardware changes in the device manager and let it auto install what it finds, sometimes running programs can mess up installs, just make sure you come offline BEFORE dropping your firewall unless you have a hardware firewall or you will get an infection, also have you installed any SATA drivers ? maybe thats what it wants, see if any of this helps.
