How to list partition table on ubuntu

Posted on December 18, 2008

Your ubuntu hard disks can be divided into one or more logical disks called partitions. This division is described in the partition table found in sector 0 of the disk.
To list your disk partition table you just need to use command fdisk in your ubuntu terminal.
Eg:

j@j-desktop:~$ sudo fdisk -l
 
Disk /dev/sda: 80.0 GB, 80000000000 bytes
255 heads, 63 sectors/track, 9726 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x00000080
 
   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           5        2299    18434587+   7  HPFS/NTFS
/dev/sda2            2300        7399    40965750    f  W95 Ext'd (LBA)
/dev/sda3            7400        8929    12289725    7  HPFS/NTFS
/dev/sda4            8930        9726     6401902+  83  Linux
/dev/sda5            2300        4849    20482843+   7  HPFS/NTFS
/dev/sda6            4850        7399    20482843+   7  HPFS/NTFS
j@j-desktop:~$

This example show us that I have one disk(sda) on my computer,and this disk are partitioned to 6 partitions(sda1~6)
