These drives are not detected by the BIOS?

First off I would try installing one at a time.

Are these second (additional) drives?

Are you installing as slaves? If so are you sure that the Master is set as Master rather than Cable Select?

Did your setup work previously? With your old drives?

the master is set
he did work good with the old drives
now he says sec master hdd error
sec slave drive atapi incompatible
