Image MASSter 4000IDE family DCO Option
(DEVICE CONFIGURATION OVERLAY)

The Image MASSter 4000IDE family unit supports copying DCO configured source drives when the DCO option is installed. DCO allows systems to modify the apparent features provided by a hard disk drive device. It provides a set of commands that allow a utility program to modify some of the commands, modes, and feature sets reported as supported by the hard disk drive. It can be used to hide a portion of the hard disk drives' capacity from being viewed by the operating system and by the file system. If DCO is detected on the source drive, the Image MASSter 4000IDE family unit's copy operation will configure the target hard disk drive with similar DCO settings.
