What if he's made copies of all the financial data you claim is on there?
What if you wipe all his stuff, then he just recovers the deleted data?
I'm guessing this guy isnt actually from the IT department right?
then again he could be, it took 1 hour and 3 DVD RW drives for the IT guy at my place to copy a DVD with some video reports on it, and even then he still couldnt manage it so i had to take it home and do it myself!!
