yes thanks everyone for answering is 12G not 8 sorry if it's default, I won't touch it then is there no way to know how many rounds a drive needs to be decrypted? if so, then that's good security but want to know how many rounds my computer would do, after the crypto has been created? I find -v gives you rounds and probably default rounds if you don't do -r, but I am too late to find out that now thanks again
