I need one urgent help.
I am using Ubuntu 12.10. My hard drive is only one year old.
Suddenly all of my folders and files became read only. After checking in Google, I came to know that this is something related to corrupt file system. I cannot transfer the files and folders to another machine or to an external hard drive. I need to back up my files immediately because otherwise I will loose many of my work.
Thanks in advance.
EDIT: Following this thread, I have performed
dmesg | less
Now I am not sure what particular error to look for, but I can see following
[ 1.844462] drm: registered panic notifier [ 1.844474] [drm] Initialized i915 1.6.0 20080730 for 0000:00:02.0 on minor 0 [ 3.082945] EXT4-fs (sda1): INFO: recovery required on readonly filesystem [ 3.082951] EXT4-fs (sda1): write access will be enabled during recovery [ 6.511793] EXT4-fs (sda1): orphan cleanup on readonly fs [ 6.511810] EXT4-fs (sda1): ext4_orphan_cleanup: deleting unreferenced inode 9962260 [ 6.511925] EXT4-fs (sda1): ext4_orphan_cleanup: deleting unreferenced inode 9966039 [ 6.511972] EXT4-fs (sda1): ext4_orphan_cleanup: deleting unreferenced inode 9966038 [ 6.511991] EXT4-fs (sda1): ext4_orphan_cleanup: deleting unreferenced inode 9966043 [ 6.553657] EXT4-fs (sda1): 10 orphan inodes deleted [ 6.553663] EXT4-fs (sda1): recovery complete [ 17.401897] EXT4-fs (sda1): re-mounted.

Following is the output when I ran fsck from recovery mode:
