Subject: Cannot access volumes mounted with 'mklink /d' which point to a volume UUID
Date: Wed, 15 Feb 2017 15:30:00 -0000	[thread overview]
Message-ID: <58A4741E.5020408@gmail.com> (raw)

On Windows you can create symbolic links which point to volume UUIDs as 
a way of mounting and unmounting them without having to use the 
administrative disk management tools.

For example, in cmd:

mountvol
...
     \\?\Volume{079b79c9-0000-0000-0000-100000000000}\
         C:\
...
mklink /d test \\?\Volume{079b79c9-0000-0000-0000-100000000000}\
...
dir test

I call mounvol to get a list of volumes and create a symbolic link 
'test' which points to the C:\ UUID. When I then 'dir test' it will list 
all files on that volume.

If I try to access it through Cygwin Bash I get the following error:

$ dir test/
dir: cannot access 'test/': No such file or directory

This makes it difficult to work with unmounted volumes as it's not 
always possible to access the administrative disk management snap-in and 
the mountvol/mklink has always been my go-to for this type of 
functionality. It would be great if Cygwin would support it.
