This is long but I have looked to provide full detail, in short my Bitlocker password and recovery key don't work - even though my password does work in a 3rd party utility.
- I was encrypting an external 2GB SeaGate drive when the power supply to my pc was unplugged.
- On restart I was unable to access the external drive with the bitlocker password i had just entered - while I found this strange as I knew what the password was - I figured I would just use recovery key.
Password didn't work
It didn't work. Which surprised me as the given the Key ID was clearly the same - see below.
It was noteworthy was that after one false attempt with the right password and right recovery key, an
x8007007a error was prompted
Further googling led me to
- The BitLocker command line tool (password failed to unlock)
- A utility from M3 Data Recovery
The M3 Data Recovery didn't access initially, but when I unplugged then plugged back in the SeaGate drive (which removed the error message re a drive error), my password did work. But this is only for the first 1GB of files, and I don't need the files badly enough to shell out $200.
From a purist sense I'm surprised that my password work in the utility but not directly, are there reasons for this and is there anything else I can try?
