Method and apparatus for predicting recovery time of hard disk drive
First Claim
1. A method for predicting a recovery time of a hard disk drive connected to a computer, said disk drive including an actuator and a spindle motor to rotate a disk, comprising:
- predicting the recovery time of the hard disk drive from a stand-by state to a usable state when the hard disk drive receives a request from the computer to exit the stand-by state; and
, reporting the predicted recovery time of the hard disk drive to the computer, wherein the recovery time is predicted with the formula;

Abstract
A method and an apparatus for predicting the recovery time required until the hard disk drive is restored to a usable state from a stand-by state. The recovery time is a time required until the hard disk drive is restored to a usable state from the stand-by state. Then, the predicted recovery time is reported to the host system. When the host system knows how much time is needed until the disk drive is recovered, it can schedule a task to be completed before the hard disk drive is restarted, thereby scheduling of all the tasks in the host system can be optimized.
