I have this problem only since the latest update:
I have an SSD drive connected through USB on a Raspberry pi 3 running Volumio. The drive no longer shows up in the music library even though it is accessible through SSH. It is also linked to /var/lib/mpd/music/USB so I do not see why it would not show up in the library.
Using MobaXterm I can also download and upload files to the USB disk so it is definitely working.
if I run dmesg there are some errors:
[ 7.976564] F2FS-fs (sda1): Magic Mismatch, valid(0xf2f52010) - read(0xc0856600)

[ 7.977131] F2FS-fs (sda1): Can't find valid F2FS filesystem in 2th superblock
how can I fix this? Why would this drive mount properly but then still not show in the library?
