Back when computers were slow enough that you could actually see them thinking. Running defrag wasn't about optimizing disk performance—let's be real, you just wanted to watch those colorful blocks shuffle around like the world's most boring Tetris game. You'd leave it running for hours, occasionally checking in like "oh nice, that red cluster moved three pixels to the left." The best part? Your drive would go from 21.80% fragmented to maybe 0.62%, and you'd feel like you just gave your PC a spa day. Meanwhile, modern SSDs are sitting there laughing because fragmentation doesn't even matter anymore. Kids today will never know the simple joy of watching 687 fragmented files slowly organize themselves while you pretend you're being productive. Fun fact: This was basically the Windows XP/Vista era's version of a screensaver, except it made your computer sound like it was about to achieve liftoff.
