Hi Charles,

I have posted the text  file at http://www.kiduvinhouse.net/share/disk.txt  Plz take a look.

I would think USB disk is partioned as "primary".  Gparted had designated the logical device name as /dev/sdc1. This is what "lsblk" prints out. /dev/sdb1 in the output is one large file system and I think this too is "primary". /dev/sdc1 is not sensed/detected by the OS.

==============================================
ramesh at mozart:~$ lsblk

=============================================

Pl let me know if I have to partition/format USB external drive (Seagate Backup) differently. 

    Thanks a lot..
Ramesh

      Hi
              Steve, Bas, Douglas,

              

              I have created a text file containing first few hundred
              lines displayed on the console. It is at:

              http://kiduvinhouse.net/share/udevadm_monitor.doc
              The first few lines are:

              Plz let me know if you need anything else.

              

              Incidentally, as suggested by Bas, I did kdesudo into
              dolphin.. A screen shot of the Dolphin GUI is at 

              

              http://www.kiduvinhouse.net/share/scrCapDisk4.jpeg

              

              

              What is displayed are the two internal HDs. The external
              drive is not listed.

              

              Douglas, I am not using any extension chord. Using the one
              that came with the unit.

              

              Thanks again,

              Ramesh

    Ramash,

    I have been glancing at this without much attention, therefore,

    I wondering if you tried:

    sudo lshw | egrep -nA 23 disk >> disk.txt

    Which will give a list of all disks the OS sees.  

    A second question, did you format the USB disk as primary?

    If you did then no OS booting off another primary disk will

    ever "see" that disk.  GPartEd will see it but it will never 

    register with the OS that is NOT booting from it.
