[SOLVED] Hard disk partitions showing up as removable devices

After a system upgrade today morning, the KDE taskbar widget that shows USB sticks and other removable devices is now showing all hard disk partitions too. Also, Wine automatically adds a bunch of virtual drives, most/all of which seem to point to the partitions/mount points I have: /, /home, /var, /mnt/windows and so on.

Is this an intended change, and what is the correct/best way to disable such behavior?

I did "udisksctl dump" which shows "Removable:" and "MediaRemovable:" flags as true for all disks.


I was suggested to add udev rules like

DEVPATH=="/devices/<...>", ENV{UDISKS_SYSTEM_INTERNAL}="1"

to set them as "internal" so that they would not appear as removable. Is it the best way, and is there anything else to do?


edit:

In KDE System Settings -> Removable devices, "Enable automatic mounting of removable media" is disabled.

Re: [SOLVED] Hard disk partitions showing up as removable devices

Same here, but i noticed no udisk package were upgraded; could this be related to kernel upgrade instead?

Re: [SOLVED] Hard disk partitions showing up as removable devices

Udisks were not upgraded in my case either, but kernel was.

I checked udisksctl on my laptop with Linux Mint, and it does not show the hard disk as removable (Removable, MediaRemovable and Ejectable flags are all false). Also, Wine doesn't set up any extra drives on that computer.

Re: [SOLVED] Hard disk partitions showing up as removable devices

Same here on a non updated laptop.
this monday I will check if downgrading kernel will "fix" it on my office pc.

Same here; downgrading the kernel back to 4.3 "solved" it.

Re: [SOLVED] Hard disk partitions showing up as removable devices

It is definitely a kernel issue, see:

# for file in /sys/class/block/*/removable ; do echo $file :$(cat $file); done

/sys/class/block/sda/removable :1
/sys/class/block/sdb/removable :1
/sys/class/block/sdc/removable :1
/sys/class/block/sdd/removable :1
/sys/class/block/sde/removable :1
/sys/class/block/sdf/removable :1
/sys/class/block/sr0/removable :1

With the old kernel i get:

/sys/class/block/sda/removable :0
/sys/class/block/sdb/removable :0
/sys/class/block/sdc/removable :1
/sys/class/block/sdd/removable :1
/sys/class/block/sde/removable :1
/sys/class/block/sdf/removable :1
/sys/class/block/sr0/removable :1

IF it is a kernel issue, it's specific to some systems.

Re: [SOLVED] Hard disk partitions showing up as removable devices

Some chipsets have the ability to mark individual ports as "Hot plug" or such in the BIOS. In Windows, this causes the drive to be treated as removable. Maybe something similar could be at work here, and the kernel just began to support it?


But whether the Constitution really be one thing, or another, this much is certain - that it has either authorized such a government as we have had, or has been powerless to prevent it. In either case, it is unfit to exist.

Re: [SOLVED] Hard disk partitions showing up as removable devices

alphaminer, you were absolutely right; disabling the hotplug functionality in the bios fixed the issue on the newer kernel.
Thanks!

This solved the problem here as well. How about hotplugging the CD/DVD drive? I didn't disable it yet as it does not show up in the device notifier.

Re: [SOLVED] Hard disk partitions showing up as removable devices

I don't know anything about device notifier. But as I understand it, hot plug is for removable devices (eg eSATA) rather than devices with removable media. So unless your disc drive is in an external enclosure I don't think hot plug should be enabled for it.

Ok, I disabled hotplug for the CD/DVD drive too. Thanks to everyone for help. I mark this as solved.

Re: [SOLVED] Hard disk partitions showing up as removable devices

If your BIOS won't let you change the hotplug flag, you can work around this with udev rules. For example:

#/etc/udev/rules.d/62-internal-disk.rules

# don't show any partition of disk sda or sdb on the desktop
KERNEL=="sd[a-b]*",ENV{UDISKS_IGNORE}="1"
# don't show any member of lvm volume group j on the desktop
ENV{DM_VG_NAME}=="j",ENV{UDISKS_IGNORE}="1"

This will also remove the devices from the 'Places' panel in Dolphin.
