Would you recomment me backing up all my data from all the existing partitions to an external Hard drive before going ahead with this?
Don't forget to archive your parts.txt file as srs5694 explained, although so long as the Ubuntuforums server doesn't fail us you now have a backup in this thread!

Yes, backing up data is a very good idea. As srs5694 said, running fixparts or sfdisk is unlikely to affect data within partitions, but it's always a good idea to make backups whenever you do any partition editing or changes. And if you haven't archived your data yet, now's the time to do it!
