If this attack succeeds, the machine will not be able to boot until the BIOS is reprogramed. For machines where the BIOS ROM is permanently affixed to the motherboard, the entire motherboard would have to be replaced. The overwriting of the sectors will not stop until the system has crashed. As a result, your computer will not boot from the hard disk or floppy disk. Any overwritten data will be very difficult or impossible to recover, even by a data recovery service.
Success is highly dependent on the size, format, partition, and fragmentation of the drive.
