It is by no means any wrong per se. And, hooking drives in whatever controllers you have in any order is, again, no wrong, PROVIDED each controller sees the drives connected to it have respective distinguishing signatures, i.e., each drive has distinct target id (and unit id, but somehow disks are always assigned unit id zero). Looking back the thread, my guess is that you connected the two drives in one controller (whichever, I don't know) giving the drives identical target id (i.e., zero). So you violated the last condition. See target id on one of the drives (maybe 3-4 dipswitches if the drives are internal ones). Change it within [1 - 6] range. (Leave one drive with target zero (to speed up bootstrapping, doh) and seven since it is the id controller has assigned to itself). horio shoichi
