There is no master/slave in SATA.
Did you re-install the amd chipset driver? Also, if you want to use the USB 3.0 ports you need to re-install that driver.
For the "large" usb drives go into Windows disk management and see if they are there, if so assign them a driver letter (they need to be attached and powered on of course).
