The ImageMASSter 4000IDE Series
supports copying DCO configured 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 ImageMASSter 4000IDE Series copy operation will configure the target the hard disk drive with similar DCO settings.
