Needs to be FAT32 or NTFS drive. I formatted mine to fat32. Works for a little while and then it has never worked again. When I connect the external usb drive with music files inside, volume cannot see the drive under “Browse”. I can only see Webradio. If I do a library/update mod database, under “Browse” RamPlay, UPNP, NAS and USB will be shown besides webradio. But the USB folder will be empty. It cannot see my files. Same with a thumdrive in the usb port. I even tried to reflash Volumio in the micro SD card. To no avail.
So now I use Volumio as a webradio only, as I can’t get it to mount my NAS. And Volumio also isn’t able to see my usb thumb drive or usb external drive. Bumber
