                            placing Disk-Validator program on disk).
                         2. Virus destroys a block by writing "LOOM"
                            over existing data; different from SADDAM v.
                         3. Virus makes Bitmap NOT VALID, so running
                            Disk-Validator next time will infect System.
                         4. Virus starts diskhead stepping in all floppy
