Which password should i use

my 4tb book with password protection cant power on despite change of adapters . i have 3 external wd discs (my book) 2TB 3TB AND 4TB usually they can share power adapters but 4tb could not power on completely. I opted to open it and connect it directly to the cpu as internal, unfortunately it could not read i opened the 2tb and changed the power board after disabling the password for 2tb now the 4tb needs a password to open but it has rejected the true password, what do i do
