This program is terrible! It always starts with that fancy screen that you can't do anything with. The defragmentation takes way too long, after 2 days it only got to 84%. When I restarted, it didn't show any drives. I tried uninstalling and reinstalling the program, now my system keeps crashing. I've been updating this program since version 18, but now with version 27, I've had enough. I'm switching to IObit Smart Defrag.
