Fomat USB Pen drive in Linux

Hi everyone,
Lot of my friends asked me that how to format pendrive in Linux.
There are many methods to format pendrive.

Solution1: 
1) Open command prompt and enter into root or su mode.
   $ sudo -su ( In Ubuntu )
   $ su - ( In RedHat )
2) Identify to which device file the pendrive is mounted
    # dmesg | tail
3) Mostly it will be sda or sdb or sdc with some number.
4) Unmount the device file on which the pendrive mounted
   # umount /dev/sdb
   Note: Please change the sdb with your above identified device file
5) Now, we can format the pendrive
   # mkfs.vfat -n 'Label' -I /dev/sdb
   Note: vfat indicates FAT32 filesystem, ext3 indicates EXT3 filesystem.
   Please change the Label with your own Label.

Solution2: 
1) Open command prompt and enter into root or su mode
   $ sudo -su ( In Ubuntu )
   $ su - ( In RedHat )
2) Identify to which device file the pendrive is mounted
   # df
3) Mostly it will be sda or sdb or sdc with some number.
4) Unmount the device file on which the pendrive mounted
   # umount /dev/sdb
   Note: Please change the sdb with your above identified device file
5) Now, we can format the pendrive
   # /sbin/mkdosfs -F32 -I /dev/sdb 

Solution3:
We can format the pendrive using GUI tool also.

1) Open command prompt and enter into root or su mode
   $ sudo -su ( In Ubuntu )
   $ su - ( In RedHat )
2) Install GParted software
   # apt-get install gparted ( Ubuntu )
   For Redhat, Please download the GParted RPM from http://packages.sw.be/gparted/
   Then install the RPM Package

   Note: Please change the version with your downloaded file version
3) Open the GParted tool
