Abstract
A method of controlling unloading of a hard disk drive, and more particularly, a method and an apparatus for controlling an unload standby time of a hard disk drive according to the accumulated number of unloading operations. The method includes: standing by for an unload standby time in an idle state of the hard disk drive; unloading a head and then counting the number of unloading operations to determine an accumulated number of unloading operations performed by the hard disk drive after the standby time is passed; and reallocating the unload standby time according to the accumulated number of unloading operations. A standby time for an unloading operation is adjusted according to the accumulated number of unloading operations in a hard disk drive such that the possibility of damaging data is minimized.
