MagneSafe V5
We can ignore the last byte because it is hex 00 and falls after the
End Sentinel.
ASCII string "+5163499080020443=000000000000? "
This is an accurate decryption of the track.

Block # 1
Appendix C tells us to decrypt the last block:
AD8C74F82F327667 TDES Dec with 27F66D5244FF621E AA6F6120EDEB427F
gets 09162DCA11E5C60B
XOR 7FD0E212B479C60B
gets 76C6CFD8A59C0000
Continue on in reverse block order:
7FD0E212B479C60B TDES Dec with 27F66D5244FF621E AA6F6120EDEB427F
gets AE81BFA4A2C80006
XOR C07B12648DCAC4FD
gets 6EFAADC02F02C4FB
Continue on in reverse block order:
C07B12648DCAC4FD TDES Dec with 27F66D5244FF621E AA6F6120EDEB427F
gets AAC8D06ACCF27E6D
XOR BE6EE7466B81196E
gets 14A6372CA7736703
Continue on in reverse block order:
BE6EE7466B81196E TDES Dec with 27F66D5244FF621E AA6F6120EDEB427F
gets 01D78CB7D1DAEA95
XOR 6F4B691E633C311C
gets 6E9CE5A9B2E6DB89
Continue on in reverse block order:
6F4B691E633C311C TDES Dec with 27F66D5244FF621E AA6F6120EDEB427F
gets 0D2620B051231748
XOR 32BA90BFB3E6B41D
gets 3F9CB00FE2C5A355
Continue on in reverse block order:
32BA90BFB3E6B41D TDES Dec with 27F66D5244FF621E AA6F6120EDEB427F
gets 41499B60A6AAD427
XOR 8628E664C59BBAA2
gets C7617D0463316E85
Continue on in reverse block order:
