help designing an optimal attack - veracrypt non-boot drive

[undeath]

Sounds like you want to do a table attack. Although you need to generate and pipe in candidates using hashcat-legacy and also patch + compile the source code yourself to remove the 16 character limit for candidates.

To have hashcat-legacy support longer passwords you have to alter

Code:

#define TOGGLE_MAX
#define TABLE_MAX

in src/hashcat-cli.c

For now I would recommend running just that attack, without accounting for possible typos.
