How to find the password for a hidden partition of a single TrueCrypt file?

[Banaanhangwagen]

as mentioned in your quoted URL you need the sector following the first 65536 bytes of the file, i.e. you need the 128th sector. Thus skip sector 0 to 127 and use the 128th.


Using a hex editor you need the 512 bytes starting with byte 65537 up to byte 66048 of the file.

Keep in mind that there is "offset 0"; starting byte will be at offset 65536 (0x10000) up to 66047 (0x101FF)
