The operating system is Windows 7 Enterprise.
I have an encrypted NTFS drive mounted at
C:\mount_point. I successfully encrypted it with BitLocker GUI (in control panel) and can unlock it with password each time I need the files. However, I found that the GUI tool doesn't support re-locking (which is actually pretty stupid).
Then I found this: Is it possible to re-lock a bitlocker drive? However,
manage-bde -lock doesn't work with a drive without a drive letter. If I run
manage-bde -lock C:\mount_point, it says "C:\mount_point is not understood. A drive letter is needed."
Thus, how should I re-lock my drive in this case, if I don't want to assign that drive a letter?
