USB-Drives are not seen

[Janvl]

Hi,

today i found out that KDE does not show the USB-Drive for mounting anymore, i tested on all usb-ports.
When i connected an external Buffalo CD-Drive i see it on lsusb with the commandline but KDE does not show it under external drives.

Anyone an idea what has happened?

had something similar happen with my linux system and /home partitions once ... turns out it was a udisk thing and my partitions had been changed to a type that is automatically hidden from the GUI because it was associated with windows restore partition type (i dual boot windows, they are on separate disks).

had to run fdisk to change the partition type to correct it.

if there is any chance windows could have touched that disk, then i would check out the partition type.

Thanks, this is a dualboot system - osses on separate disks and i did read from the windows disk and vice-versa.

with the drive connected can you see it using

lsblk

note the path designation to the partition where the data is located and then use

sudo udisksctl info -b [path-to-partition]

that should result in a list of particulars and at the bottom will be a Type: designation

look up that designation code on this website and see what it says

https://uapi-group.org/specification...specification/

if it is listed as anything other than a linux data partition then you need to use fdisk to change it back to something the GUI will allow

for my mounted media trove i used type 20

I must rephrase my question.
With KDE I always became a popup when a USB-Device was connected, then the choice to mount it. This Popup does not show up anymore.
With lsusb the device is listed.

I'm going to guess that you may have disabled the System Tray entry Disk & Devices.

The System Tray has a ^ (Show hidden icons) at it's right side. Right-click on it and select Configure System tray...

Click on Entries.

Find Disk & Devices. Make sure it is set to Shown when relevant.

Hi,

I had a look at the systemtray and its configurations and i do not see anything disabled. I checked the settings and i have automount activated for removable media.
With lsusb i can see for example a usbstick but it is not mounted and not even proposed by KDE to mount it.

There is a list with media that have been mounted in the past but it is greyed out.

Anyone have another idea?

The KDE Partition-editor does not show media that are not mounted.

Perhaps you have hit the problem I reported in all btrfss on removable drives fail to mount with 25-10? Underneath, udisks complains that I do not have permission, so no popup is generated; changing permissions on the drive does not help.

So. what filesystems are on the external drives?

The drives can be mounted from the command line, so long as I don't try to mount them using "Disks & Devices" from the system tray. If I do try, the drive goes into an error state that is only cleared with a reboot.

My workaround has been to put the drives in /etc/fstab with options noaudo,user. For example,

LABEL=noah    /mnt/noah          btrfs   noatime,noauto,user                0 2

(Having created /mnt/noah.) With that, when I plug in noah, it appears in dolphin's Places side bar, and if I click it there it mounts and I can use it normally.
