2. Check Out newly created partition

bash-4.2# fdisk -l
#
#  Output Truncated
#

Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes

Disk label type: dos
Disk identifier: 0x000c08b7

   Device Boot      Start         End      Blocks   Id  System

Thanks a lot. This was exactly what I was looking for. Other blogs are very confusing but this worked for me line by line.

If you could add, how to add this partition to fstab so every time I boot my linux machine it gets picked up automatically, would be helpful.

Well described tutorial. Thanks again.
