Well usually it should, but not always.

Here is the partition table:

Disk /dev/sda: 80.0 GB, 80032038912 bytes
255 heads, 63 sectors/track, 9730 cylinders, total 156312576 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: 0x0004a073

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *        2048   152350719    76174336   83  Linux
/dev/sda2       152352766   156311551     1979393    5  Extended
