I will try swaping the >ribbon cable headers first and will followup as soon as I find the solution (or >the lack thereof :) In conclusion: If you have the afforementioned problem after you get all the jumpers set it is most likely that your cables are "flipped". It appears that df1: (the original internal drive in my case) needs to have the "pass-through" ribbon connector and df0: (the newly installed drive) needs the ribbon connector at the end of the cable (the one with two of the wires flipped). BTW: Make sure that you get the connectors onto the drives correctly as well. Most drive ribbon cables that I've seen have a red strip on one end. This is to denote the wire that "belongs" to pin one on the drive connector. My drive's pins weren't numbered so I had to guess but doing it wrong a couple times didn't appear to damamge anything. Now that I've done this, the drives function _exactly_ as expected. This is great, I wish all solutions could be found in a day :-) That's it, -Beej
