Hi james_b,
when you share a directory tree that has mount points within it (/mnt/MPD/ shared as music_store),
it is normal for a free space report to be about the filesystem at the root of that tree only.
In our case root is the sd card.
This is only a cosmetic problem, and should not prevent writing.
On Windows:
- \\RuneAudio\music_store\NAS will report the correct size
- \\RuneAudio\music_store will report the size of your sd card
