just step back a little bit.
grab a new HDD/SDD put a LUKS encrypted and working operating system or data on it. make sure that the encryption and decryption works with that disk. Remember the password for it.
Given this example / test disk, you can now extract the bytes that you need and try to run it with hashcat by using a small password list that also contains the correct password that you used for this test.
If it works, you have successfully recovered the password for this test with hashcat and you can be quite confident that it should work the same way for your target partition / disk.
Of course hashcat only print the correct password if the password candidates you are running also contain the correct password (could of course be mangled with rules etc, but it still needs to be one of the passwords hashcat tries).
