Volumio not recognized extended HDD

Help and Support Help
1

My setup: Pi3 + BossDAC + USB 16gb + HDD 2.5" 500GB (I copied some albums to both USB and HDD)
Software: Volumio 2.296 (latest)
I plug USB and HDD via USB port, browse volumio on my phone but Music Library only show USB albums. While I can access both in /mnt/USB/

Sorry for my bad English.

I founded that mpd takes too much resource (cpu/memory), turn off resample by edit /etc/mpd.conf can fix it.
