You don't have to do that unless you are worried about getting confused. If you put the drive on a machine that already has da0 used up, it will magically become da1. The label doesn't have anything to do with whether it is da0 or da1. That is determined by its position on the controller. I think, in FreeBSD SCSI device stuff, you can force it to be something, but I have never done it and don't know how - and since it doesn't matter, don't see the reason to try. ////jerry > > TIA, > > James Smallacombe PlantageNet, Inc.
