/dev/sdx always changing...

[Rexilion]

How are the disk listed in /dev?

[Jean-Claude Tergal]

Thank you for the answer.
Here is the content of /dev:

cyrille@ordi-cyrille:/dev$ ls -la | egrep 'hitach|sd'
brw-rw----   1 root disk      8,   1 oct.  20 10:43 hitachi1
brw-------   1 root root      8,   0 oct.  20 10:42 sda
brw-------   1 root root      8,   1 oct.  20 10:42 sda1
brw-rw----   1 root disk      8,  16 oct.  20 10:43 sdb
brw-rw----   1 root disk      8,  17 oct.  20 10:43 sdb1

brw-rw----   1 root disk      8,  80 oct.  20 10:42 sdf
brw-rw----   1 root disk      8,  96 oct.  20 10:42 sdg
brw-rw----   1 root disk      8, 112 oct.  20 10:43 sdh
brw-rw----   1 root disk      8, 113 oct.  20 10:43 sdh1

Is this what you expect?

Bad news, the /dev/sd* are somewhat arbitrary by design, they cannot be changed.

Look: http://lists.us.dell.com/pipermail/l...st/040049.html

And here: http://askubuntu.com/questions/12769...rive-in-dev-sd

The fact that KDE partition manager still shows the partitions 'as is' is a good thing since you don't want to mess with that (imagine formatting the incorrect disk since the labels overlap!).

I guess that KDE partition manager still fetches the info from an ioctl() or from /proc/partitions (which are not under control by udev).

However, your problem with the "Hard disk status" plasmoid still stands in the fact that it should show all disks. That is a bug. I was under the impression you could work around this with udev. But I was wrong about that. Sorry for that.

So, change the sdx is not so easy.
It's not really a problem for me.
I leave them as they are.

The workaround for the plasmoide is to delete the line contain 'uuid' in ~/.kde/share/config/plasmadesktop-appletsrc.

It was very interesting to exchange about udev with you. I've learn a lot.

Certainly.

I will soon alert the developper of this plasmoid about this problem.

Thank you.
