If you are serious about recovering this TC volume your only hope is to remember the format of the password. If you are the one who created the password, you should have some idea of what it was. If you truly can't remember any part of the password (or you are trying to crack someone elses password), just quit now because there is no hope.
Make a list of all the parts you think the password could be made of. Names, numbers, special characters... Then make a table of all these and start trying combinations. If you remember most of the password you may be able to guess the rest in less than 100 tries.
If you can't narrow it down that much, you will need to run brute forcing software. This automates the guessing process, possibly trying 1000 guesses per minute.
