In a method for denying unauthorized access to data stored in a computer data storage medium of a computer, a product serial number of the storage medium is read and processed to generate a locking signal that is recorded when setting a status of the storage medium to a locked state. When a disarm input is supplied by the user of the computer, the disarm input is converted into a converted signal that is compared with the locking signal. The user is allowed access to the storage medium when a match is detected between the converted and locking signals, and is denied access to the same when otherwise.
