Abstract
In a technique for restoring data damaged by a computer virus on a magnetic information recording disk in a hard disk drive, booting information required to boot the hard disk drive and file position information indicating the position of a file when data is stored in a file unit are backed up in a predetermined portion of a maintenance area on the disk. The booting information or the file position information is restored based on the backed up information when the booting information or the file position information is infected with the computer virus.
Claims20
A process of ameliorating damage to a recording disk by a computer virus, comprising the steps of:
- dividing an information recording disk into a maintenance area with limited access to a user, and a data area with general access to the user, with said data area being separate and discrete from said maintenance area;
- storing within said maintenance area, a back-up of system information stored within said data area of the recording medium;
- and
- after the system information stored within said data area is infected by a computer virus, restoring said system information of the recording medium by using the system information stored within said maintenance area.
A process of ameliorating damage to a recording disk by a computer virus, comprising the steps of:
- dividing an information recording disk into a maintenance area with limited access to a user, and a data area with general access to the user, with said data area being separate and discrete from said maintenance area;
- storing within said maintenance area, a back-up of booting information required to boot a computer reading information from the recording disk;
- storing with said maintenance area a back-up of file position information indicating a position of a file stored within said data area of the recording disk;
- and
- after one of the booting information stored within said data area and the file position information stored with said data area is infected by a computer virus, restoring the infected one of said booting information and said file position information by using a corresponding one of the booting information and the file position information stored with said maintenance area.
An apparatus for restoring data stored on an information recording medium that have been damaged by a computer virus, comprising:
- an information recording disk comprising a maintenance area with limited access to a user, and a data area with general access to the user, said data area being separate and discrete from said maintenance area;
- and
- a circuit accessing said information recording disk to store within said maintenance area, a back-up of system information stored within said data area of the recording medium, and after the system information stored within said data area is infected by a computer virus, restoring said system information of the recording medium by using the system information stored within said maintenance area.
