What are the GB sizes of the drives in the order that you replaced them?
It is possible that there isn't enough electrical power to run the drives or there is a problem with the power connector going into the drives or the drives themselves.
Check with a voltmeter to see that you have 5Vdc and 12Vdc running through that cable.
Check to make sure you have a secure connection and no shorts.
It is possible the drives themselves were all bad, defective or such with that type of symptom. But it's happening with all the drives. Run Disk Utility or Tech Tool Pro or some king of drive utility app to make sure the drives are truly okay.
