External USB drive not detected under mOode 6.4.0 - Smallwire - 01-14-2020
Hi all,
I have come to this forum to see if anyone is able to shed some possible insight to the problem I have been experiencing. I have recently updated to mOode version 6.4.0. Since updating to this version, I have encountered a problem where my external USB drive cannot be detected, thus I am unable to play songs that I have stored on this drive through mOode Audio and I am only able to play via streaming radio sources. Oddly enough, I did not experience this issue on older versions (around version ~5-ish).
Has anyone experienced similar issues where the external USB source cannot be detected? Could this be a software issue, or perhaps a hardware issue?
I would like to add a few more details:
- I have a Pi3 with a Katana DAC on top of the Pi.
- I am reluctant to say it is an issue with my external USB drive, since I can recognize it on my computer.
Any assistance/insight is greatly appreciated. Thank you.

For a start, with your USB drive plugged in, reboot then post the output from the commands below.
Code:
lsusb
ls -l /mediaRE: External USB drive not detected under mOode 6.4.0 - Smallwire - 01-14-2020

Did you update mpd database ?

I can see the external drive through the command (Toshiba) but it is not detected on the mOode UI.
The empty /media directory indicates the drive was not auto-mounted by udisks-glue.
Couple thoughts:
- udisks-glue does not run on arm6 platforms (Pi-Zero, 1B). You can switch to devmon auto-mounter in System Config
- the drive needs to have a disk label to be auto-mounted
- some drives need to be externally powered

I see, thanks for your reply. You're right, I do not see the drive under /media.
In response to your thoughts:
- So, I've tried Devmon today, and that still did not work.
- I also gave it a disk label via ntfslabel on my computer (since it is an NTFS drive). Even after doing that, I couldn't get it to show up on my Pi under /media, or even looking at /dev/disk/by-label (and the other options)...
- My drive should be an internally powered drive.
I also tried looking at the mpd logs (/var/logs/mpd/log) and system logs (/var/logs/syslog), but didn't really see anything pertaining to my drive there either. Though, the system log did mention that my "Toshiba" drive was detected but nothing more.
Is it the case that I simply cannot listen to the music through an external source on this version, then? Is there some sort of manual mounting procedure or something?

@Smallwire
No, this version---6.4.0---works just fine with an external USB drive.
You said you have an RPi3 (model A, B, B+?) with a Katana DAC on it. The devmon fix isn't necessary because udisks-glue works fine with this model.
You said "My drive should be an internally powered drive." Does this mean your drive has its own power supply?
Tim's point is that some drives draw too much current to be powered by the Pi via the USB cable so that either a self-powered disk or a disk connected via a powered USB hub is required. If a hard disk, the worst case is during spin up. The USB interface could be working but the disk itself not responding properly.
The disk should be seen in a variety of system output.
For example, considering a small USB-connected SSD on one of my moOde players, hostname moodeLR:
1. it's a partition in fdisk output
Code:
pi@moodeLR:~ $ sudo fdisk -l
...bunch of moOde partitions...
...this one is mine...

3. It's in the list of filesystems in Linux
Code:
pi@moodeLR:~ $ mount

...I'm curious if you see one or more "Mass Storage" bInterface Class occurences in the voluminous output from this lsusb command (where I took the vendorID:deviceID values from your lsusb output and assumed your Pi's hostname is "moode")

RE: External USB drive not detected under mOode 6.4.0 - vinnn - 01-15-2020
A nice simple command to list block devices is 'lsblk'.
As Kent is saying OP, if you can't see the device listed in the output lsusb or lsblk then it's most likely that the disk requires more power to spin up than the Pi or it's power supply can supply.
RE: External USB drive not detected under mOode 6.4.0 - TheOldPresbyope - 01-15-2020
Doh. I keep forgetting lsblk (in my defense, it was created long after I "learned" Linux). As @vinnn says, it's nice and simple.
Adding it to my previous post
Code:
pi@moodeLR:~ $ lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 119.2G 0 disk
└─sda1 8:1 0 119.2G 0 part /media/MUSIC
sdb 8:16 1 244M 0 disk
└─sdb1 8:17 1 243M 0 part /media/CorePlus
mmcblk0 179:0 0 14.9G 0 disk
├─mmcblk0p1 179:1 0 256M 0 part /boot
└─mmcblk0p2 179:2 0 14.6G 0 part /sda1 is the sole partition on my USB SSD and sdb1 is the sole partition on a USB memory stick.
Neat!

Kent
