I recently purchased a Unitek USB 3.0 to IDE+SATA Adapter. When I plug the first 500gb Hitachi HDD into the adapter I get a pop up window saying check device information fail. Check device status. Windows gives me an error message telling me I need to format the drive before I can use it. The second 500gb HDD when plugged in does nothing. The two HDD's come from an Alienware M17R4 with the drives in a RAID configuration.
