Can't access from ubuntu to windows 8 drives that install along side it

Windows 8, by default, hibernates instead of fully shutting down (read: to allow for fast boot). It's a pain but I believe if you tell windows to reboot into the special "Advanced Options" mode in the settings then you could potentially tell windows to shutdown fully. Check out this link to shut down your windows 8 pc fully (link to another question click here for their tutorial they found to disable fast boot).

Running the command mount -t ntfs-3g -o ro /dev/sda1 /media/sd4 makes it read only hence the ro. Change that command to mount -t ntfs-3g -o rw /dev/sda1 /media/sd4 for writing.
