Then you make sure the SCSI IDs are differnt (may need a jumper or two for this), connect the two drives and the mac to the 3-connector ribbon cable (where the 2-connector one is now), connect the power up, and things should work fine, except your disk is probably not in a particularly stable (mechanically) position. What I did when I wanted to connect two internal drives together, though, is I used an external drive enclosure, took the drive that was in there out, put the new internal in there, and transferred the info. Then I put the original drive back. Obviously, this is only an option if you have an external drive around. I don't know what the power budget of the Mac IIci is-- I know the IIci can take some of the big (power hungry) Wrens inside, so as long as neither drive is one of those, you are probably safe. -- Matthew T.
