bitlocker

I use a USB key which is encrypted with BitLocker to store various data. I keep that key with me all the time.

What happens all the time is that I send my home computer to hibernate without ejecting the USB key first. Then I unplug the key and take it with me to work. When I get home, I resume my Windows session and even though the key is not plugged in, the drive still appears as mounted on the system.

I can also unmount the non-existing device with mountvol, but that only removes the drive letter. Windows will still think the device is plugged in. When I plug the key in, nothing happens.

The device's class ID is listed in mountvol output, but the device is not listed in the Disk Management panel.
