using cygwin with an encrypted external drive

Keeler, Lisa
Hello,

I love Cygwin, and have used it for many years so that I can use emacs, grep, and all other useful linux tools against my Windows file system.

I have the latest version of Cygwin:  2.903  64bit

Previously, I had an external passport drive which was not encrypted, and I was able to use it in Cygwin just fine, no problem, using /cygdrive/d/...

Now, my external passport drive has been encrypted by McAfee encryption, per policy for my company.

Now, I can see the files OK on the Windows File Explorer, but when I look at the /cygdrive/d in Cygwin, I see nothing useful at all.

Below is a comparison between what I see in Cygwin -vs- what I see from a Windows command prompt:
