The drive is formatted as ext3, and does not have an entry in fstab. Since this drive is apparently internal (you didn't say it was external), let's create a mount point and add it to fstab.
Let's say you want to call it "storage" (you can call it whatever you want, just don't use spaces or special characters in the name).
Make the mount point
Now open fstab for editing
sudo mkdir /media/storage
At the bottom, add this line:
gksudo gedit /etc/fstab
Save and close. Now remount the drive (if it complains, post the output back here):
UUID=75566192-0cb2-4b96-b288-c856b02c04d9 /media/storage ext3 defaults 0 2
Now set ownership on the drive (where you subsitute your login name for <yourusername> without brackets):
You should now be able to write to the drive.
sudo chown <yourusername>:<yourusername> /media/storage
