How We Doubled Floppy Disk Space on the C64 💾

If you had a Commodore 64 in the eighties, you probably did this.


A single-sided five and a quarter inch floppy only gave you six hundred sixty-four blocks. So we punched a second notch in the disk and tricked the 1541 drive into thinking it was double-sided.


Risky? Yes. Worth it? Absolutely.


Did you notch your disks… or were you too nervous to try?

👇 ABOUT FLOPPY DEEP DIVE 👇

Hey, it's Tom from Texas! Floppy Deep Dive is dedicated to Real Hardware and Real Nostalgia. No emulators. No filters. Just the crackle of the CRT and the mechanical grind of the disk drive.


I make these videos for the folks who spent Saturdays swapping floppies and still get chills when the SID chip kicks in. We dive deep into the Golden Age of PC gaming, reignite the classic 8-bit wars (C64 vs Atari!), and hunt down the rarest software on earth. Whether you're Team Commodore, Team Atari, or just miss the 90s, you're in the right place.


The Mission: Preserving the sights, sounds, and "craptacular" quirks of classic computing before they fade away.


🕹️ What You'll Find Here:


The Hardware: Commodore 64, Atari 800XL, Amiga, 486 PCs, and more.


The Wars: C64 vs Atari/NES comparisons (Let the debate begin!).


The Hunt: Deep dives into mysterious floppies and forgotten games.
