A 3.5-inch floppy disk holds 1.44 megabytes. That is roughly 90 seconds of music compressed as an MP3 at a decent bitrate. It is also, as Ukrainian software engineer Oleg Kutkov demonstrated in a recent experiment, enough to get a Tesla to play a song from a storage format that predates the fall of the Berlin Wall.
“I just wanted to see if it would work,” is the kind of impulse that drives experiments like this, though Kutkov has not offered a detailed public statement about his motivations beyond the technical documentation of the project itself. What is clear is that the result surprised observers across the tech press.
Kutkov plugged a standard 3.5-inch floppy drive into his Tesla’s glovebox USB port using a USB-to-FDD converter, a small adapter that makes legacy floppy hardware appear as a generic USB mass-storage device. The car’s infotainment system recognized the drive, read the diskette, and played the MP3 file stored on it. No jailbreaking, no custom software, no tricks beyond the converter cable. Tom’s Hardware documented the experiment in detail.
Why it worked
Tesla’s infotainment system runs on a Linux-based software stack. The Linux kernel, the core of the operating system, still ships with a floppy disk driver. That driver is classified as “orphaned,” meaning no single developer actively maintains it as a primary responsibility, but it continues to receive periodic code cleanups. A recent patch series tidied up the driver’s internals, as Phoronix reported with links to the upstream kernel patches.
Because the driver is compiled into the kernel by default, any Linux-based device that does not explicitly strip it out can, in theory, talk to floppy hardware presented over USB. Kutkov’s setup exploited that chain: the converter made the drive look like ordinary removable storage, and the kernel already knew what to do with it.
Tesla’s own Model 3 owner’s manual describes USB flash drives as the intended media source, with supported formatting such as exFAT and specific guidance on which ports handle data versus charging. The manual also notes changes for vehicles manufactured after approximately November 1, 2021. Nowhere does it mention floppy drives. The system accepted one anyway.
What we don’t know
Several details remain unclear. Kutkov has not publicly specified the exact make and model of the USB-to-FDD converter he used. Whether the Tesla required any software tweaks, or whether the car accepted the floppy drive entirely out of the box on stock firmware, is not fully documented in available reporting. Tesla has not commented on the experiment or indicated whether floppy drive compatibility was ever tested as part of the vehicle’s media pipeline. Kutkov himself has not provided a quoted reaction or extended commentary beyond the technical demonstration, leaving the piece reliant on third-party reporting rather than firsthand remarks.
There is also the question of reproducibility. Kutkov’s success may reflect a specific firmware version rather than a universal capability across the Tesla fleet. Tesla’s build process could strip or disable certain kernel modules on some software releases, and without access to the company’s build configurations or a broader survey of vehicles, it is impossible to say how many Teslas would behave the same way. Owners tempted to replicate the setup would be experimenting on their own vehicles without manufacturer guidance.
On the safety side, connecting unvetted hardware to a vehicle’s USB port could, in principle, introduce unexpected behavior in the infotainment system. No reporting describes any adverse effects from Kutkov’s test, but a single successful demonstration does not confirm safety across different models, firmware versions, or floppy drive hardware.
Floppy disks in places that matter more
A floppy drive playing music in a car is a novelty. A floppy drive feeding data to an air traffic control terminal is a national safety concern. As of spring 2026, both situations remain part of the technology landscape.
The U.S. Federal Aviation Administration has been working to retire legacy technology from critical infrastructure for years. In testimony before the House Appropriations Subcommittee on Transportation, FAA Acting Administrator Christopher Rocheleau addressed the agency’s fiscal 2026 budget request, which includes modernization efforts targeting systems where decades-old storage formats have lingered far longer than in consumer electronics. The White House has separately outlined plans to overhaul the U.S. air traffic control system, with senior officials telling the Associated Press the effort will cost “lots of billions.”
The connection between Kutkov’s hack and the FAA’s challenges is thematic, not technical. No government official has drawn a direct line between hobbyist experiments and the push to retire legacy storage from aviation systems. But both stories illustrate the same underlying dynamic: old technology rarely disappears cleanly. It lingers in drivers that no one quite owns, in interfaces that still function “well enough,” and in infrastructure that is too risky or costly to overhaul on any quick timeline.
The bigger picture
Kutkov’s experiment is charming precisely because it is low-stakes. Nobody’s safety depends on whether a Tesla can read a floppy disk. But the reason it works points to something worth paying attention to: general-purpose operating systems carry enormous amounts of legacy code, and when those systems get embedded in cars, medical devices, industrial equipment, or government infrastructure, that legacy code comes along for the ride.
The Linux kernel’s floppy driver has “orphaned” status, meaning it receives maintenance but not the kind of structured, rigorous testing that safety-critical automotive software typically demands. Whether Tesla’s engineering team audits every inherited kernel module, or whether some simply pass through because they do not cause obvious problems, is a question the company has not publicly addressed.
For now, the takeaway is simpler and more fun than any policy debate: if you happen to have a 3.5-inch floppy disk, a USB adapter, and a Tesla, you can listen to about 90 seconds of music on a format that debuted when Ronald Reagan was in office. The car will not complain. It might even be the most patient audience a floppy disk has found in decades.
