Windows 10: forget the bitlocker PW

Dear my old harddrive hasn't use 5years ago I forgot the passwork and no recovery key how can I find to access? thanks

Bitlock PW does not work anymore

Hi there, first, I am German, not the most technical person and you are my last chance, to rescue some very important data. So excuses my English and thanks a lot for any attempt to help me.Here the problem: After connecting my HDD with a friend’s computer, it was automatically locked by Bitlocker. At first no Problem at all, because my friend could name me the PW his computer has given my HDD. This worked out well for 3-4 month. However, one day, I entered the PW and Bitlocker told me, that it is wrong. However, it was not. I copied it; I entered it manually... many, many, many times. It did never work. Of course, my friend looked again in his online PW list, if something changed, but it did not.What I find very interesting, if I enter the correct password, Bitlocker says it is wrong. If I change only one of the 48 numbers, it tells me, one number is wrong. If I change it back, its again totally wrong.Any ideas what might help? Would be great, if somebody has a solution. Otherwise, four TB of data are lost.Thanks’ a lot!
