Using DiskPart to clean up hard disk partitions and MBR is fast and easy but you can accidentally invoke a full format which can take a while to finish. In that case, instinctively you would press Ctrl+C only to find that you've just killed DiskPart instead of stopping the format process.
Googling around, people suggest to kill the process using task manager (which you can't) or reboot your system. There is yet an other option, which worked for me, and no one mentioned (at least on the sites I checked).
