Curiouser and curiouser ... why?
What happens if, when you format the sticks, you give them the same 'label', and use that? (And perhaps use the label as the "mount point name" too).
Well, I want to be able to plug in any USB stick containing my data, and expect to find it at the same mount point. Is this unreasonable? If I understand correctly, using UUID would not allow this, and using the 'label' seems an unnecessary restriction, though it might be a work around.
When I said earlier that I thought a USB memory stick wouldn't have any partitions, I meant of course that it would normally only have one, primary partition.
So I still dont understand why in one case, it appears as "/dev/sda", and in another as "/dev/sda1"..
