Thank you for sharing your experience. TBH we are so guilty of doing things quickly, especially when they are tasks that we are quite familiar with. I'm so glad that you didn't corrupt the hard drive. Excellent pointers for anybody wishing to edit partitions. 

The one thing that I always do is put the swap and boot partitions etc at the start of the drive and then have my root followed by the home. This means that if I need to resize then it doesn't need to move the partitions, this has been where I've had the majority of issues in the past.

It shows how much distros have changed over the years, Brasero used to be included with them all but nowadays the majority of computers come without optical drives.
