I acquired this at a yardsale, and i paid a measly $2.50 for it, before i do anything with it, what does it do, and is it safe? i booted it on another computer and it said if i found it to take it to bestbuy and taunt geek squad with it. anyone have a similar disc and knows what it does. after 4 years in computer repair i have still yet to come across anything like this.
