I'm not sure I understand.

You're testing with -d <non-existing-folder> if the drive is unlocked?
And you're expecting... what exactly?  The test should return FALSE in
all cases, regardless of the drive being locked or unlocked.

Sure, it sounds wrong if -d <non-existing-folder> returns TRUE, but
I wonder if I misunderstand what you're doing.

Can you rephrase this to make it more clear?

Also, can you create an strace of the wrong behaviour to see if there's
a certain error or NT status code which indicates the problem to be
handled more correctly?


Thanks,
Corinna
