General :: Cannot Copy File Even As Root (Permission Denied)

I am attempting to make a backup copy of a file, but every time I try to copy the file, I get a "permission denied error -- even when running as root. The file is on a volume mounted as /media/Data . No problems reading/writing other files on the volume.

Here is the info on the file:
-rw-------. 1 root MailServer.img

I've tried chown but get the permission denied as well. This is a virtual machine image that runs fine, but even with the VM completely shut down, I get the same error.
