Cannot mount USB / doesn't automount after power crashed

English Hardware
#1

Looking for help with USB removable thumb drive.
Lost power and the computer went down, when it restarted the USB will not mount.
Any help is appreciated.

leap 42.2 -

Below are the results on my system to:

udisksctl monitor Monitoring the udisks daemon. Press Ctrl+C to exit.
21:38:11.454: The udisks-daemon is running (name-owner :1.36)

When I removed the USB thumb drive it added:

21:38:47.449: Removed /org/freedesktop/UDisks2/block_devices/sdd1

21:38:47.482: Removed /org/freedesktop/UDisks2/block_devices/sdd

I plugged it back in and it did nothing. Unplugged it, and this time nothing changed.

The devices shown are my 3 hard drives and the DVD/CD.
The USB is plugged in, but not detected or showing.

Tried to mount sdd and sdd1, but nothing.

Will not mount the usb thumb drive.

#2

When it is not detected as before, I assume some hardware problem (due to the power outage) in that USB or the device itself. Try another USB mass storage device on that USB and/or try to put the device into another USB if there are more on the system.

And of course when there is no /dev/sdd1 created, it is rather useless to try to mount a file system on it.
And /dev/sdd is the whole disk and as it is partitioned (one partition) there is of course no file system on /dev/sdd itself, thus that will never be mountable, created or not.

#3

With the suspect device plugged in what is reported by the following?

sudo /sbin/fdisk -l

In fdisk -l (list) above I noticed there is an sdd.
I created a folder in /mnt named /usb and was able to manually mount that drive sdd1

So the files are there, but the automount is still not functioning. When I plug in the device it is not registering or loading. Can we still get that fixed?

thanks for your help.

That’s good to know. Any errors on it?

So the file system is FAT32.

Run the following as user

udisksctl monitor

and plug in the device. Capture the output.

  1. So, nothing specific to the device reported when you plugged it in? Just to confirm that you did plug it in after the monitoring command?

  2. Run

dmesg --follow

then report back with the kernel output generated when you plug the device in.

  1. Can you mount the device with udisksctl (as user)?
udisksctl mount -b /dev/sdd1

Confirm that it is mounted with

mount|grep sdd

or with

df -h
  1. How is the device seen by udev?
udevadm info -a -p $(udevadm info -q path -n /dev/sdd1)

did not understand that, sorry. So when it was removed is showed:

21:26:36.833: Removed /org/freedesktop/UDisks2/block_devices/sdd1
21:26:36.834: Removed /org/freedesktop/UDisks2/block_devices/sdd

when I plugged it back in, nothing.

I am running the other tests now. Will reply in a minute.

It took awhile, but it looks like it may have shown up:

The above output isn’t complete…at least it shows the device was handled by udisks though.

It does mount ok… perhaps when you plugged in to a USB 2.0 port?

I changed to a different port and is showed up. Figure that?

Do you have a mixture of ISB 2.0 (EHCI) ports and USB 3.0 (XHCI) ports perhaps?
