Yes, this trick works.
But the problem with it is that this should be done without such 'dd' 
command. User should be relieved from issuing such meaningless command 
since system can do this automatically, avoiding user actions and 
possible user confusion.

Driver knows when disk is inserted (for example in Windows autorun 
executes when disk is inserted). This should be used in this case.
