Take the 2-minute tour ×  I have a external hard disk and
protected a partition on it with Bitlocker To Go. I printed the
recovery code but I lost it. I can't remember the user PIN
either. If I could only know the first characters of the PIN,
I'm sure I would remember the rest. I work on a Windows 7 x64
system. The TPM was not enabled when I activated Bitlocker. I
only used a recovery key and a user PIN with more than seven
characters.  My question is: Does a (brute force) software exist
that can find (the first) characters of the PIN (user password),
or is the information on it lost?  I know the recovery password
can't be brute-forced in a million years. I only hope it's
possible to find a few digits of the pin so I'll remember the
rest of it.  share|improve this question  1 Answer 1  It's not
possible to find arbitrary digits of the pin. It's an all-or-
nothing deal.  Assuming a numeric pin, there are 10,000,000
possible combinations. Depending on the implementation of the
key derivation algorithm, it may ta
