Subject: Issue when trying to access files on a locked BitLocker volume
To: cygwin@cygwin.com
Content-Type: text/plain; charset="UTF-8"

Hi,

I'm using a Bitlocker encrypted SD card, which stays most of the time in my
laptop, but is generally not unlocked. I'm unlocking it only when I need to
access files on it.

I have also a script which is started at regular intervals, which copies
some critical files on the SD card when it is unlocked. I was using till
recently a *very* old version of cygwin (probably downloaded 10 years ago),
in which I could check whether my SD card was unlocked or not by using *if
[ -d <folder-on-SD-card> ]*. I have downloaded a new version of cygwin in
January, as I migrated to Windows 10 and was encountering some issues with
it. Since I upgraded, this test is not working anymore. When the SD card is
unlocked, testing " -d <folder> " returns TRUE. It returns FALSE when I do
the same test on a non Bitlocker volume for a non-existent folder (which is
the expected behaviour).

I guess there are probably other issues related to accessing locked
Bitlocker volumes.


If someone is wanting to solve this, don't hesitate to contact me if you
need more details or if you want me to make tests.


Kind regards,

   Vincent
