Bring back the era when a single typo at the C: prompt could vaporize your homework. This simulator recreates the black-on-green terror of FORMAT.COM.
CRT glow, monospace characters, and the ominous question: “WARNING, ALL DATA ON DRIVE C: WILL BE LOST.”
The screen boots into a faithful MS-DOS replica with BIOS memory counts, floppy seek sounds, and the blinking underscore cursor. Type anything and the system reacts with old-school syntax: format c:, dir /s, john.exe. When it “formats,” sector counts fly across the screen, cylinders get enumerated, and a fake percentage ticker accelerates dangerously fast.
The console understands classic DOS commands and responds with realistic prompts, errors, and confirmation dialogs.
A brief POST screen scrolls by, setting the tone before the FORMAT utility appears.
The formatting phase lists clusters, bytes per allocation unit, and total disk space like original DOS messages.
Optional floppy whirs and PC speaker beeps for anyone nostalgic about beige towers.
Press F11 so the black background fills the monitor. Adjust brightness down to mimic CRT glow.
Enter format c: or format d:. The simulator prompts, “Proceed with Format (Y/N)?”
Press “Y” with a sigh. The system begins counting sectors while you shake your head.
Mutter phrases like “I hope we have backups” or “That’s the production drive.” It spikes adrenaline instantly.
Before anyone dives for the power cable, exit fullscreen, smile, and explain the throwback prank.
In the 80s and 90s, formatting was irreversible. There were no recycle bins or cloud backups. Seeing FORMAT.COM meant hours lost. That memory still jolts anyone who lived through it. Younger audiences, meanwhile, experience pure curiosity—“people really did this?”—making it educational and funny.
Write a few pages of mock documentation describing the “proper” way to execute a format mission—include diagrams of jumper settings, coffee break schedules, and an oath swearing to label backup tapes. Hand the booklet to your audience before the prank starts so they feel like accomplices, then stamp it “Mission Accomplished” once you reveal the website.
format and the UI updates accordingly.Ctrl+C and it will simulate an interrupted command.Invite friends to improvise the backstory of the doomed hard drive. Was it the accounting system? A top-secret project? Grandma’s recipe archive? Passing the narrative baton keeps everyone laughing while the “format” counter climbs.
For extra flair, sketch a fake backup plan on a whiteboard behind you: “1) Panic, 2) Call tech support, 3) Blame Steve.” These visual gags turn a single-screen prank into a full scene worthy of a sitcom cold open.
Chart the legendary evolution of storage while the fake format bar crawls. Write milestones on sticky notes—5.25" floppies, ZIP drives, Jazz cartridges, USB thumb drives—and peel them off dramatically as though the computer is erasing tech history.
Keep a shoebox labeled “Emergency Backup Tools” filled with blank CDs, Sharpies, antistatic bags, and a fake manual titled Disaster Recovery 1998. When the format screen appears, open the box with exaggerated seriousness and hand out props. Suddenly your prank becomes a live-action drill, complete with “tape rotation schedules” and “offsite vault runs.”
Create a one-page “newsletter” describing imaginary software bugs you’re allegedly fixing with this format. Print headlines like “Spreadsheet Server Overrun By Tamagotchi Simulator” and pin it near the monitor. Onlookers love reading the lore while the sectors tick by.
Teach the room a call-and-response (“When do we back up? Every night!”). Chant it as the format percentage climbs. The silliness cements real data-hygiene habits.
Set up a mic and pretend to interview “system engineers” about what went wrong. Give them prompt cards with ridiculous failure scenarios (“Hamster chewed the SCSI ribbon”). Their improvised answers add dozens of extra laughs.
Point a short-throw projector at translucent curtains or fog screens to create volumetric rain. Drape sheer fabric in doorways so guests literally walk through digital code. Photographers love combining the projection with slow shutter speeds for painterly portraits.
Never use this prank to threaten coworkers or imply real data loss. The fun lies in nostalgia, not stress. Reveal quickly, and maybe teach someone what DOS used to look like.
