There are two HDD (sda and sdb) on my computer. I installed ubuntu 12.1 on "sda". And I mounted to /home "sdb". Desktop-->above menu bar-->Go-->Computer-->2.0 TB Hard Disk(sdb)-->Unable to mount location. I want to access "2.0 TB Hard Disk(sdb)" from there (Go-->Computer). How can I mount it?

physics@physics:~$ sudo mount /dev/sdb5
mount: /dev/sdb5 already mounted or /home busy
mount: according to mtab, /dev/sdb5 is already mounted on /home

I typed fdisk -l on terminal:

Unmount the /dev/sdb5 and mount it inside a directory in /media so that the drive appears on the unity bar.

sudo umount /dev/sdb5

create a directory inside /media folder by running below commands,

cd /media
mkdir hdd 

Then mount the dev/sdb5 in the hdd directory by running the below command,

sudo mount /dev/sdb5 /media/hdd

You can't able to delete the files inside /dev/sdb5,because it was your /home partition.

physics@physics:~$ sudo umount /dev/sdb5 umount: /home: device is busy. (In some cases useful info about processes that use the device is found by lsof(8) or fuser(1)) – ahmedo047 Dec 20 '13 at 12:06
sudo umount -l /dev/sdb5 – ahmedo047 Dec 20 '13 at 13:00
you can't unmount sdb5 because it is your home partition.plz explain what you are trying to do. – Avinash Raj Dec 20 '13 at 13:13
if it works means then accept my answer. – Avinash Raj Dec 20 '13 at 13:26
Firstly Avinash thanks for your helps. sudo umount -l /dev/sdb5 cd /media mkdir hdd sudo mount /dev/sdb5 /media/hdd I solved the problem using above commands. But there are two folder in sdb5, named "physics" and "last+found". I dont want to any files related to ubuntu there. I will use as a "program store" it. it must include anything about ubuntu. But I should be able to access it. – ahmedo047 Dec 20 '13 at 13:32
