There's currently a bug I'm investigating / working on a fix for that involves the SD card not mounting reliably if it's inserted whilst the device is running. That's likely why a hard reset was what got the card to be recognised in the first place. Until that gets fixed in the firmware, I'd suggest putting the SD card in before turning the device on to minimize these sorts of errors. Sorry for your frustration, hopefully it won't take long to fix.

If the card doesn't show even after a hard reset it's likely another issue (possibly caused by the first though, if the card was repeatedly ejected/mounted). Database corruption can cause this, as can the card becoming corrupted. Try deleting the database and recreating it (`.tangara-db/`folder on the sd card, if it exists delete it and its contents). If that doesn't work, you may need to reformat the card.

Thanks for the info and suggestions! I'm afk for the weekend, will try all that when I get home Monday...
