Abstract
A method of prefetching data in a hard disk drive includes searching for a logic block address (LBA) of data requested by an external apparatus in a history of a non-volatile cache of the hard disk drive, and if the LBA of the data is stored in the history, storing data recorded in a LBA stored after the LBA of the data requested by the external apparatus from among LBAs stored in the history in a buffer of the hard disk drive.
