1. circuit of protecting data on hard disc, it comprises:

  • One first hard disk connector, it connects the hard disk connector of computer main frame panel;

    One second connector, it connects hard disk;

    A hard disk signal processor, it connects this first hard disk connector, this second connector, reaches a microprocessor;

    One random access memory, it connects this microprocessor;

    One has the non-according to electrical semiconductor memory of program code, wherein this program code can be carried out by this microprocessor, making this computer main frame panel hard disk connector is corresponding to the read/write signal order in the virtual data space of this hard disk corresponding to the master file space read/write signal command conversion of this hard disk and when the virtual data space of this hard disk data was destroyed, this circuit can be written into this virtual data space again with the master file space data of this hard disk.
