摘要

Hard disk controller is connected to a computer and a disk via data leads and contains completely isolated disk areas that can be associated with separate virtual PCs. The controller stores data relating to the active hard disk area and the sequential hard drive area. Address data is converted by the controller to a disk address and access is only allowed if the address refers to the currently active area.
