Apparatus and method for protecting data on computer hard disk and computer readable recording medium having computer readable programs stored therein

A method for protecting data stored in a hard disc of a computer system, the method comprising the steps of:

• (a) dividing a hard disc area in the computer system into a system protection area, a user data area, and a system change area;
• (b) operating the computer system in a protection mode;
• (c) storing changed content in the system change area in response to a write request with respect to data stored in the system protection area and accessing both data stored in the system protection area and the changed content stored in the system change area in response to a read request with respect to data stored in the system protection area so as to determine the data corresponding to the read request, in the protection mode;
• and
• (d) recovering the hard disc by deleting content from the system change area when the computer system satisfies a predetermined condition.

A computer readable recording medium in which a program, through which a computer system operates such as to protect data stored in a hard disc thereof, is recorded, the program comprising:

• a hard disc dividing module for dividing a hard disc area in the computer system into a system protection area, a user data area, and a system change area;
• a data protection module for storing changed content in the system change area in response to a write request with respect to data stored in the system protection area and accessing both data stored in the system protection area and the changed content stored in the system change area in response to a read request with reflect to data stored in the system protection area so as to determine the data corresponding to the read request, during operation of the computer system;
• and
• a data recovery module for recovering the hard disc by deleting content from the system change area when the computer system satisfies a predetermined condition.
