This is very valid, although the list of exceptions which I listed above muddies the waters. The simplest way to look at it is to consider the case of libusual absent. Then, the list of devices which ub supports is given with one line which matches 8/6/50. When we are armed with libusual, we can make the safe set more precise by including devices which mistakenly specify 0xff somewhere and by excluding that non-disk, pure SCSI adapter by Adaptec. So, the comment would not be too long, and it does not need to list exceptions as I did for illustrative purposes. Still, I'm having difficulties formulating it. I have to think about it a bit more. You and Alan seem not to have any difficulty figuring it out from just the code, so I hoped to let it slide :-) -- Pete ------------------------------------------------------- Using Tomcat but need to do more?
