# test3_bad1.tar:    byte at offset  259 changed from 't' to '0' (magic)
# test3_bad2.tar:    byte at offset 1283 changed from 't' to '0' (magic)
# test3_bad3.tar:    byte at offset 2559 changed from 0x00 to 0x20 (padding)
# test3_bad4.tar:    byte at offset 1283 changed from 't' to '0' (magic)
#                    byte at offset 2307 changed from 't' to '0' (magic)
# test3_bad5.tar:    510 zeros + "LZ" prepended to test3.tar (bogus lz header)
# test3_bad1.tar.lz: byte at offset    2 changed from 'I' to 'i' (magic)
# test3_bad2.tar.lz: byte at offset   49 changed from 0x49 to 0x69 (mid stream)
# test3_bad3.tar.lz: byte at offset  149 changed from 0x2D to 0x3D (mid stream)
# test3_bad4.tar.lz: combined damage of test3_bad2.tar.lz and test3_bad3.tar.lz
# test3_bad5.tar.lz: [71-134] --> zeroed (first trailer + seconf header)
# test3_bad6.tar.lz: 510 zeros prepended to test3.tar.lz (header in two blocks)
