    Have to unlock BitLocker volumes twice to gain access


    Win8.1 Pro x64

    Been having a weird problem lately. Whenever I unlock a BitLocker volume (I have two of them), I can't access it. The system doesn't even provide a drive letter. If I try accessing the drive letter in Directory Opus (where the drive letters are always shown, whether the volumes are unlocked or not), I get an error saying the drive does not exist.

    But if I lock and immediately unlock the volume a second time, all is well.

    I don't understand this at all. Anyone?

    No one? This has to be one of the stupidest, strangest problems I've ever encountered--and I've been using Windows for ages.

    I changed the password on both BitLocker volumes, but it didn't make a difference to this issue.

    I'm not sure, but I think this problem may have been due to EMET. After removing EMET, the problem went away. I have no idea why EMET would interfere in this way. I have found EMET to be more trouble than it's worth even if it wasn't the cause of this issue.
