摘要： The present invention relates a method for accelerated scanning of a disk drive for media damage caused by rough handling. In the method, a current cylinder number is set to an initial target cylinder number. Data is read from a track associated with the current cylinder number and is checked for an error indicative of media damage. The current cylinder number is then set to a next target cylinder number that is equal to the current cylinder number plus a cylinder skip factor. The skip factor causes the current cylinder number to change by more than one cylinder number. For the new current cylinder number, the reading and checking steps are repeated. Unlike a full media scan that attempts to read all of the tracks of a disk drive, the accelerated media scan method of the invention skips tracks by skipping cylinder numbers to reduce the scan time while maintaining a great deal of certainty that media damage is detected. If media damage is detected, then a full media scan may be performed to determine the scope of the damage. Significant cost savings may be realized due to reductions in testing time provided by the accelerated scan method.

摘要： There is disclosed a method of operating a disk drive for enabling a host computer to assist in rescuing a rescue-candidate location having drive-unrecoverable data. The method includes identifying a selected addressable location as a rescue-candidate location if the selected addressable location contains drive-unrecoverable data, and recording the logical address of the rescue-candidate location in a list. The method further includes transferring the list to the host computer via an interface in response to a list-requesting command from the host computer, and responding to a write command from the host computer to write host data to a selected rescue-candidate location having a logical address recorded in the list such that a subsequent read operation can recover the host data. There is also disclosed a method of operating a computer system for enabling a host computer to assist in rescuing a rescue-candidate location having drive-unrecoverable data.
