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?

  • What do you gain from not assigning the volume a drive letter? – Ramhound Apr 15 '16 at 20:19
  • @Ramhound Windows allows me to do so, why cannot I just like it? – bfrguci Apr 15 '16 at 21:50
  • Toggle offline/online in Disk Management? – Tom Yan Apr 16 '16 at 7:46
  • @TomYan that is a physical partition on my hdd. I don't think I can toggle the only hdd on my PC. Can I? – bfrguci Apr 16 '16 at 21:25
  • It's actually possible with offline volume in diskpart. You'll need to remove the path for the volume (e.g. with mountvol /D) first though. So I guess you can script a bit with them. Btw manage-bde -lock PATH works AT LEAST as of Windows 10 10586. – Tom Yan Apr 17 '16 at 3:38
