If there was already a device scanned at that id, you have to remove it first. And it is not hard to do a for i in 0 1 2 3 4 5 6;do .... done > start from scratch.

In that period no other scsi device can be accessed. So it is a wasted 1/4 of a second. Usually you know what the id is. So writing a simple script, even a rescanscript is simple. Now if it only was THAT easy in windows 95...
