Abstract
A Virtual Disk Storage (VDS) System for providing multiple virtual data storage devices for use in a computer system which contains a central processing unit (CPU). The VDS System includes a memory system for storing information and a VDS Controller which is in communication with the memory system and the CPU. The VDS Controller partitions the memory system into multiple virtual data storage devices, and then restricts the computer system from communicating with certain of these virtual data storage devices. The VDS Controller thus selectively isolates at least one of the virtual data storage devices from communicating with the computer system, in order to prevent corruption of information stored in at least one virtual data storage device.
