Authentication method of hard disk drive and recording medium storing the same

A method of authenticating a host system by a hard disk drive accessed by the host system, the method comprising:

• forming authentication information, wherein the host system forms the authentication information based on information read from the hard disk drive;
• transmitting the authentication information to the hard disk drive when the hard disk drive accesses the host system for a first time;
• storing the authentication information transmitted from the host computer for the first time in a maintenance cylinder, which can be accessed only by the hard disk drive.

At least one computer readable medium storing instructions that control at least one processor to perform a method of authenticating a host system by a hard disk drive accessed by the host system, comprising:

• determining whether authentication information received from the host system is identical to authentication information stored in the hard disk drive;
• and
• blocking access of the host system to the hard disk drive until the hard disk drive is turned off if the authentication information received from the host system is not identical to the authentication information stored in the hard disk drive.
