Hi fugieguys,

Thanks for the link however, the solution was far more simple than.

Dell failed to mention in the owners manual (as far as I can see) that the SATA ports are set to 'OFF' by default.

You need to enter the BIOS to turn on your respective SATA port before adding any hard drive to your system.

Oh.

The cable I show above is not needed for your rack to be functional other than to animate the LCD display on the front.
