No USB 3 Drive visible but drive is mounted

Hi

Congratulations for your software!
I’ve the same problem of a similar Topic. Mine is little different.
I tried to attach a UBS3 HDD disc (no ssd) to Raspberry Pi3.
I’m a Linux user so a formatted this HDD in ext4 (but I don’t think this is the problem)
The hdd is well mounted as I checked in console (under /media …) and folders& files are visible but in Volumio webpage it is not visible.
The HDD is good and I’ve unmounted it before attaching into Pi3.

any solutions ?

thanks

PS I’m Italian and, in particular, I’m ‘fiorentino’ too. Is there any forum, or the way to contact you, in our language?

Certo! Michelangelo at volumio dot org

solved by myself: volumio can’t read extr4 partition.
USB3 HDD run good !
