GNU parted is not capable of moving a partition
into a position that overlaps with the original,
so I suspect you are using "gparted", a different tool,
that *is* capable of doing what you describe.

It just so happens that Curtis Gedak described
gparted's move algorithm just a couple weeks ago:

I'd start by trying to determine how far the move proceeded
before it was interrupted.  You'll probably have to write code to
compare src/dest sectors until you find a pair that differs.
Once you know that, you may be able to complete the task.
