How to access music stored on a USB drive (SSD)

Hi, I have installed Volumio3 on an old mini PC (Celeron 1017U), and it’s running fine. However, I can’t access music stored on a USB (EXT4, gpt) drive:
In the Volumio GUI, the drive doesn’t show up, searching in “My music” results in 0 files.
However, when I log in via ssh, I can access the drive, create & delete files, etc. So it is mounted correctly (at /media/UUID). Hence, my question: Does the drive, or folder (there’s not only music, but also other stuff on the drive, therefore a few subfolders) needs to have a special name? I did search the FAQ, but I couldn’t find if there needs to be a special naming.
Thank you very much!

Hi,

have a look at this post
It will answer your question

Hi gkkpch,
thank you very much for your reply! Ahh, I actually didn’t find that requirement when I searched - sorry for that. Sadly, it still does not work: I labeled the volume to issd, now the drive gets mounted to INTERNAL, instead of USB as before:

lsblk -f
NAME   FSTYPE   LABEL        UUID                                 FSAVAIL FSUSE% MOUNTPOINT
loop0  squashfs                                                         0   100% /static
sda                                                                              
|-sda1 vfat     boot         9CC8-09A7                              88.1M    48% /boot
|-sda2 ext4     volumio      eb55ffab-19d3-41c1-ba5a-6467611e98a1    1.3G    56% /imgpart
`-sda3 ext4     volumio_data 5150c78d-bb55-4219-a857-d922a8e325ff                
sdb                                                                              
`-sdb1 ext4     issd         2e583573-eac7-44c0-9aa2-451ac1ac606f  854.2G    48% /data/INTERNAL
or paste code here

I can access all my files via ssh, but the volumio gui still can’t find them. Is there e.g. a systemdlog that could help?
Thank you very much!

please have a look here

most probably the disk does not have a partition table

It does have a partition table, gpt type. Maybe something went wrong when I ceated it? (But I never had problems with gparted before, and my Debian work machine didn’t complain ever - the drive is old.)
fdisk -l says “Disklabel type: gpt”

As Volumio is Debian based, I’m puzzled. Do you know where the configuration settings for the Volumio behavior are located? Perhaps the label restrictions etc. can be simply switched off.

You need to submit a log, otherwise this becomes just a game of guessing.
