512 bytes is correct. (every other size is wrong, the details are explained here: https://hashcat.net/faq#how_do_i_extract...pt_volumes)
(but note: hashcat doesn't give a warning/error if the file is longer and has "valid data" i.e. at least 512 bytes... it will just consider the first 512 bytes)
You should use dd instead of hex editors.
Converting the data to hex is wrong.
I'm pretty sure you are using the wrong file etc (your are mixing Hash.txt with Hash1.txt,Hash2.txt,Hash3.txt,Hash4.txt etc in your command above)
if you have a look at the examples for veracrypt from the example hash wiki page, they all use binary (raw) data... not hex encoded data.
