Protective device against computer-viruses and external charged with spying attacks on the hard disk during the online - or mains operation of the computer

摘要

The system requirements are for a computer with at least two IDE-(AT bus) hard disc droives 4,6. In order to protect the data one drive 6 is temporarily made unaccessible when on line and this drive is coupled to a controller 2 via a switch 8. This prevents any access to important information over the network. A restart is required before the drive can be accessed.
