Was this typed correctly? If you have more than one drive on the same cable they cannot both be jumpered master. Once must be slave. The one on the very end should be jumpered master and the other slave.
Same deal with any type of drive i.e. cdroms and dvd roms. The one on the end has to be master and the other must be slave.
The bios should find all your drives if they are set up correctly and they are not damaged. Make sure you put the connector in the right way. The red stripe must be on the side that the molex power connector is on.
