USB hard disk formatted as hpfsplus not being auto-mounted

Hello, I am attempting to use Volumio as my music server and am not able to have my USB hard disk auto-mounted. I have added the following packages: hpfsplus, hpfs-utils and xfat-fuse. I have two different drives containing duplicate copies of my library that I have been trying. The first is an hpfs file system and the second is xfat. Neither drive is being mounted at start. All entries under /mnt/USB show nothing.
Any thoughts would be appreciated.

Hi, only FAT32 and NTFS supported, from what I could figure … beginner here though.
