Ubuntu – How to mount a partition – Unix Server Solutions

I am new to Linux and don't know anything about mounting. This question is related to df -h doesn't show /dev/sda. What comments teach me is the partition is not mounted. So, how to do that, since I have no idea of it. I am scared of damaging something accidentally.

Output of lsblk is :

NAME    MAJ:MIN  RM   SIZE RO TYPE MOUNTPOINT
 sda        8:0    0   100G  0 disk
 vda      253:0    0    60G  0 disk 
  vda1    253:1    0    60G  0 part /
  vda15   253:15   0     1M  0 part

The o/P of sudo fdisk -l /dev/sda is:

Disk /dev/sda: 107.4 GB, 107374182400 bytes
255 heads, 63
sectors/track, 13054 cylinders, total 209715200 sectors
Units =
sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512
bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x727b8bb7

I don't understand why the 100G of sda isn't available. If I have to mount it then HOW?

Best Answer

/dev/sda is a disk, not a partition. A partition identifier contains a number, e.g. /dev/sda1. It looks like you have no partitions on your sda drive. You have to create at least one partition on the empty disk, format it and then mount.

There is a well-written guide at https://help.ubuntu.com/community/InstallingANewHardDrive mentioning all the options, just follow it carefully.
