The drive contains a single primary partition which windows 8 disk management identifies as Healthy when the drive is attached via a usb 2 controller.
In this mode I can read and write to the drive.
But when connected to the SATA controller system will not boot.

The drive contains only a single data file until I added a text file to it via USB connection.
