Hello,

Recently Dolphin shows illegal drive I never mounted it before and when I click on that drive I got this error message:

Code: Select all

An error occurred while accessing '*', the system responded: The kernel driver for this filesystem type is not available.: Error mounting: mount: wrong fs type, bad option, bad superblock on /dev/sda5,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

May some one help me to fix this issue?

tell us about the partition

Code: Select all

fdisk -l /dev/sda

it could be corrupt because of a crash or such, if so this looks like a good tutorial for fixing a corrupt ext4 file system, obviously if it's a diff file system the instructions would be somewhat different http://linuxexpresso.wordpress.com/2010 ... in-ubuntu/

have you rebooted to see if that clears this?

try:

swapfoff /dev/sda5
swapon /dev/sda5

what is
