Hard drive locked

[bussinessmenss]

My son in all his wisdom put a password on his hard drive. Gateway 7330GZ notebook. You guessed it, either he typed it wrong twice or just forgot it. Boot up screen says "Hard disc locked enter password"- As it is now, it makes a good paper weight. Any sugestions, Gateway support says to send it to them $$$$$ Trying to maybe do it ourselves. Please help!!!!!!!
Thanx
