Hi, I have a few Linux containers on Windows Server 2019 which bind mounts a folder in the D: drive. I am able to read from it, but gets a System.UnauthorizedAccessException when attempting to write/overwrite a file to it. Is this a known / expected behavior? If it is, is there any way that permissions can be changed for the Docker containers to write to it?

   Can you please update ACL on the folder, e.g.

   Switch-DockerLinux
   mkdir D:\host | Out-Null
   icacls D:\host\ /grant "everyone:(OI)(CI)M"
   docker run --rm -v D:/host:/host busybox touch /host/sample.txt
   

   Please let us know if this works for you and if not, please help us with a repro scenario.
