ABSTRACT:
The content of a hard disk drive or the like information storage media that includes content stored in a host protected area (HPA) or reserve area of the hard disk is duplicated using hard disk drive duplicating machinery. The duplication process includes the steps of detecting the presence of a HPA on a source drive, and if detected, generating an HPA are of the same or of a sufficiently accommodating size on the target disk drive. Information from the source HPA drive to the thus created HPA area of the target-drive. The remaining content from the source drive is written to an available section of the target drive. The invention is thereby able to detect whether a source drive has a HPA, create an HPA on the target drive, and to copy the content of the source HPA to the HPA on the target device to ensure a proper duplication of the target drive.
