Go directly to the (real) source:

http://support.wdc.com/product/download.asp?groupid=609&sid=113

"6. The software will scan the Serial ATA bus and automatically update 
the hard drive that is connected and recognized."

and

"Note: If you are having issues updating the firmware of a drive 
connected to a PCI Serial ATA controller or Serial ATA RAID controller, 
please install the drive into a system with Serial ATA connections 
directly on the motherboard (Onboard Serial ATA controller) and try again."

It only works directly on the SATA bus.
