ABSTRACT:
A method for controlling a disk drive includes: detecting an amount of an impact applied to the disk drive, and determining whether the detected amount exceeds a critical value; reading position information of a cylinder, over which a head is positioned, when the detected amount exceeds the critical value, and suspending a command being implemented; determining whether the read cylinder number exceeds a reference cylinder number; and moving the head in an innermost peripheral direction of the disk when the read cylinder number exceeds the reference cylinder number, and moving the head in an outermost peripheral direction of the disk when the read cylinder number does not exceed the reference cylinder number.
