Damage..............: permanent damage: overwrites bootblock; simulates
                         standard bootblocks when examined with any
                         tool; destroys blocks by overwriting them
                         with an endless sequence of the ASCII string
                         'Lamer!!!', which will cause a read/write
                         error on the affected storage media.
