Method and apparatus for predicting recovery time of hard disk drive

摘要

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.
