Usually, a cable select cable will be marked primary or master, secondary or slave, and maybe motherboard, at each of the 3 plugs. In addition, they usually have a small hole somewhere in the cable . If it is marked this way, you must use the CS jumper settings on both hard drives. Otherwise, the jumpers designate whether the drive is a master or slave. . Usually, the hard drive will have a small picture or markings showing the pins needed to make each setting. Sometimses you will see cs (cable select) sl (slave) and ma (master) printed above or below the pins, sometimes on the circuit board.

I am sorry I did not state that I set the jumpers on both drives and I placed them with the master at the end of the cable and the slave in the middle. I will try setting both drives to "cable select". I did everything according to Seagate's instructions. I cannot think of anything else. Help would be appreciated. > Jim Cooley > Do you want to signoff PCBUILD or just change to Digest mode - visit our web site: http://freepctech.com/pcbuild.shtml
