ABSTRACT:
The personal computer hard disk protection system is designed to protect data stored on computer hard disks while permitting multiple user operation. The personal computer hard disk protection system prevents unauthorized access to the hard-disk controller by software applications, and permits safe servicing of requests which use the BIOS. The basis for the personal computer hard disk protection system functions is the dynamic transformation of the file system to the configuration of the current user. The system is based on a hardware device called the protection-program support module and a set of protection programs, most of which is stored in the protection-program support module. The protection program support module is an external board and is connected to the computer system bus.
