Hi bnilsson,
there are two things to check:
- the mount directories /mnt/MPD/NAS and /mnt/MPD/USB
If there are old mount points delete them.
For example, you have an old mount point called volume.
ls /mnt/MPD/USB
rm -r /mnt/MPD/USB/volume
- next thing is to delete the old USB mounts in the database
redis-cli del usbmounts
Normally this only happens when you shutdown the device and then remove the USB thumb drive.
You should go to Menu->Sources and click on the USB-drive you want to remove.
After doing this you can remove it physically.
NAS mounts can be removed also from the sources page.
