[sudo] password for johndoe:
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel

Changes will remain in memory only, until you decide to write them.
After that, of course, the previous content won't be recoverable.

Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)

Configuring Ubuntu to Automatically Mount a Filesystem

In order to set up the system so that the new file system is automatically mounted at boot time, an entry needs to be added to the /etc/fstab file. This may be edited by issuing the following command in a terminal window:

sudo gedit /etc/fstab

The following example shows an /etc/fstab file configured to automount our /photos partition:

# /etc/fstab: static file system information.
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
proc            /proc           proc    defaults        0       0
# /dev/sda1

# /dev/sda5
