I have to protect a company development laptop that contains important corporate information that I do not want to be read by anyone when it travels around the world. What I am looking for is a simple mechanism that during the Windows 2000 system boot up a prompt is given to enter a password. If the correct password is entered the system boots up as normal (eg. BIOS type password security) however if an incorrect password is entered the whole hard drive contents are deleted permanently by either silent formatting or silent fdisking the partitions (eg. cannnot be recovered ever!) Should an incorrect password by entered a screen prompt that would hide that the drive is being deleted would be good, a message to say that the password is being checked. Also a limited number of entry times would be good. Anyone got any clever ideas?
