I'm copying a partition I had on a virtual disk (VirtualBox) to a real disk. I ran GParted on the virtual machine and copied the main partition (12.98 GiB) over to the new disk, and during the copy I inflated it to fit the entire disk's space (~500GiB) and leave only 1.8 GiB free for swap.
The first step in the process was to delete the currently existing partition on the disk, and then the copy process started. Now it seems to be completed (the progress bar says "12.98 GiB of 12.98 GiB copied") but the bar has been wiggling around with no sign of progress for the last 20 minutes:

What does this mean? Is it safe to terminate the process? Do I have to do anything else?
