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.
