A habbit we have frequently seen is that mapped network drives gets given a low driver letter in the alphabet. Is there any reason NOT to give a mapped network drive a high drive letter? For instance, the site we work with wants to use E and G as the drive letters would correspond with the name of the data they are going to be used to hold on those drives. Right now any flash drives or external drives plugged into those machines grabs those letters. Is there any reason it's a bad idea or bad practice to (after removing all external media) assign a mapped network letter to the higher letters?
