is there power to the drives? check fuses and voltages. This also may sound dumb, but, un-plug everyhing (universal reset) and try to power everything up again.
do you know what form the communication is between the drives and the control software? there could also be a problem with comm.
good luck, let us know how you are making out, post pictures of your set up too , sometimes a picture is worth a thousand words....... |
