    EXT4/fd (sda1): previous I/O error to superblock detected during boot

    Hello, I am using Ubuntu 11.10 32 bit. Yesterday, my computer had some line error during boot-time, showed EXT4/fd (sda1): previous I/O error to superblock detected (screenshoot : http://i.imgur.com/TMow5UU.jpg). On this condition, my compie still could reached Desktop, but then, my Desktop showed a dialog window with unreadable-character, (screenshot : http://i.imgur.com/YmljPwk.jpg). After that, it wouldn't show the Unity and some shortcut folders on Desktop became unknown-file-like (screenshot : http://i.imgur.com/OJJZvC2.jpg).

    Could any body tell me what is this and how could I get rid of it?

    I might first try fsck to see if that repairs issues with partition.

    #From liveCD so everything is unmounted,swap off if necessary, change example shown with partition sda1 to your partition(s)
    #e2fsck is used to check the ext2/ext3/ext4 family of file systems. -p trys fixes where response not required
    sudo e2fsck -C0 -p -f -v /dev/sda1
    #if errors: -y auto answers yes for fixes needing response see man e2fsck
    sudo e2fsck -f -y -v /dev/sda1
