Title:
  incorrect management of damaged external hard disks

Status in “gparted” package in Ubuntu:
  Incomplete

Bug description:
  Binary package hint: gparted

  There is a case where Ubuntu is very bad : when nothing works !

  Here we have a gorgeous example which concern HAL, nautilus, and
  gparted .

  On my hard drive I have 3 partitions, one of them is formated by ext3 but it's damaged.
  When I plug my hard drive, nautilus is able to open others 2 partitions, but not the 3th partition. 

  There are some error messages :

  Unable to mount 156.2 GB Media
  DBus error org.freedesktop.DBus.Error.NoReply: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.

  and

  Cannot mount volume.
  Error org.freedesktop.DBus.Error.NoReply.
  The message did not receive a reply ( time out by message bus )

  On nautilus there are not the arrow ( which appear when the partition
  is mounted ) right next to the 3th partition, so the 3th partition
  will not be mounted ( as I think, as it should be ).

  To repair it , I use Gparted but Gparted don't like this error and
  runs in a loop on "Scanning all devices ..." ( Issue#1 )

  I can't use gparted to repair this error !! What can a lambda user do to fix this if gparted not works ?
  Anyway, I test some solutions :

  First of all I close gparted ( which runs in a loop ) , and I launched
  it again.  But no window appear ! On terminal I have :

  sudo gparted 
  error: libhal_acquire_global_interface_lock: org.freedesktop.Hal.Device.InterfaceAlreadyLocked: The interface org.freedeskdesktop.Hal.Device.Storage is already exclusively locked either by someone else or it's already locked by yourself

  Apparently Gparted is not normally close ( however I close it with the
  cross ). I guess it still scanning all devices ... ( Issue#2 )

  So I kill it  !! yeahh

  menoft at menoft:~$ sudo killall gparted
  menoft at menoft:~$ sudo killall gparted
  menoft at menoft:~$ sudo killall gparted

  (==> no "gparted: no process killed" !! )

  gksu need to be killed before !! Aha ! ( issue#3)

  menoft at menoft:~$ sudo killall gksu 
  menoft at menoft:~$ sudo killall gparted
  gparted: no process killed

  But gpartedbin persist ! ( issue#4 )

  menoft at menoft:~$ ps -A | grep gpart
   7146 ?        00:00:09 gpartedbin <defunct>

  
  menoft at menoft:~$ sudo killall gpartedbin 
  menoft at menoft:~$ sudo killall gpartedbin 
  menoft at menoft:~$ ps -A | grep gpart
   7146 ?        00:00:09 gpartedbin <defunct>

  menoft at menoft:~$ sudo kill -9 7146
  cps -A | grep gpar
   7146 ?        00:00:09 gpartedbin <defunct>

  I don't understand !!

  In addition I need to kill hal-lock ( gpartedbin depend of this )

  menoft at menoft:~$ sudo killall hal-lock

  AND at the end , after all this manipulations, gparted can be launched
  again ( very complicated :-) ) but I don't do this.

  After some manipulations ( open/kill gparted ), check what I have :

  ps -A | grep gpar
   7146 ?        00:00:09 gpartedbin <defunct>
  10700 pts/0    00:00:07 gpartedbin <defunct>
  13246 pts/0    00:00:05 gpartedbin <defunct>
  15833 pts/0    00:00:16 gpartedbin <defunct>
  16310 ?        00:00:00 gpartedbin <defunct>
  16987 pts/0    00:00:00 gpartedbin <defunct>

  Looks very nice , isn't it ?

  Now I will talk about nautilus !

  When I want umount other partitions, I have this message  ( writing
  data to device, ... ) but arrays not disappear and drive still mounted
  ! I must umount manually all partition because it not works with
  nautilus. When I do this and after the unpluging drive, partitions
  don't disappear on nautilus ( issue#1212121 ) ( directories don't
  remove in /media/ ! )

  Finally with the mouse, it is impossible to fix this, I open a
  terminal and do this :

  sudo fsck /dev/sdb1
  [sudo] password for aslan: 
  fsck 1.41.3 (12-Oct-2008)
  e2fsck 1.41.3 (12-Oct-2008)
  fsck.ext3: Device or resource busy while trying to open /dev/sdb1
  Filesystem mounted or opened exclusively by another program?

  Ok , I got tired, so I've restarted my computer and I do all fixing
  manipulation on console mode after killing gmd

  sudo fsck /dev/sdb1 works ! And it fixed all problems on my partition.

  Now on graphic mode, this not works ! fsck not works correctly. But I
  will fix this later.

  Thanks for reading.
