I had to recover my Win 7 desktop from an image file on an internal drive. I have scheduled to save a disk image on a regular basis. I previously had mapped the two disks in the NAS (Volume_1 and Volume_2) as N: and O:. Now N: shows up in Windows Explorer, but O: does not. The NAS does not show up under Network, but it does on my laptop 9 (also Win 7). I can access folders on N: from my desktop and laptop, but only O: on the laptop.
