* Open your Grub boot menu.

sudo nano -w /boot/grub/menu.lst

* Look for the Defoptions and Altoptions and make them look like the entry below.

# defoptions=quiet splash rootflags=data=writeback
# altoptions=(recovery mode) single rootflags=data=writeback

* You need to update your Grub since you have altered it.

sudo update-grub

* Now we are going to edit the Fstab because it will be expecting these options.

sudo nano -w /etc/fstab

* Now you are going to want to add the (data=writeback and noatime=0) flags to your hard drive. It might be a little confusing because of the new naming system. Look for the (,errors=remount-ro) and add it afterwards to make it look like our example.

defaults,errors=remount-ro,data=writeback,noatime 0

* Now you tell your system to use them both.

sudo tune2fs -o journal_data_writeback /dev/yourdrive
