No idea. Can you be more specific? Exactly how is it mounted?
Thanks for the heads up. The next version will. Thankfully exiv2 has some support for the format. If there are limitations in its support let me know. It might be that ExifTool can be roped in to help read the metadata.
If you mount it so it is addressable on your file system, then you’ll have considerably more luck. However, if you do this, depending on your download speed, you need to ensure that it’s possible to reliably copy files to it at high speed. With some network shares that requires tuning the mount directives.
