It’s Now Imperative That You Copy That Floppy | Hackaday

In the early 1990s, Don’t Copy That Floppy was an anti-piracy campaign that attempted to connect with computer-savvy youth through the power of hip-hop. While somewhat difficult to imagine given our current draconian Digital Rights Management (DRM) hellscape, warning kids about the potential legal ramifications of duplicating floppy disks containing copyrighted software was seen as necessary since at the time there was usually nothing preventing users from simply copying the contents of one disk to another.
Unfortunately 30+ years down the road, we’re now finding that somebody really should have been backing up some of those disks. Which is why the University of Cambridge of launched the Future Nostalgia project and produced Copy That Floppy! — a phenomenal guide on preserving the contents of floppy disks while we still can.

The problem isn’t just that modern computers don’t have floppy drives. The disks themselves degrade with age, a process which is accelerated if they aren’t stored properly.
As such, Copy That Floppy! only briefly touches on the most ideal situation — that is, buying a USB floppy drive and making copies of the bog standard 3.5 inch disks you might come across. It then moves right on into more advanced topics, such as interfacing with less common drive types, how to safely clean floppies, and the use of advanced tools such as Greaseweazle to analyze captured disk images.
We’ve seen demonstrations of some of these techniques before, and a few years back Adafruit got interested in floppy preservation with modern hardware. But in-depth guides like these that pull all that information together into one place are valuable resources.

…and the result was hilariously cringeworthy because while money-wielding, fork-tongued lizardmen coexist within our society, they don’t really understand it.*

Unfortunately, the presence of AI-generated video and quick easy A/B testing allows one to effectively influence a population without even speaking their language. The current state of advertising on social media is that you can give a brief LLM prompt ("Convince people that the earth is flat") and the system will take it from there. It will generate a few video ads, display them to users, pick a winner based on engagement rate, tweak the ad slightly, test again, repeat, repeat. All while you sleep. No human insight or empathy necessary.
Right now, in my demographic, the main efforts appear to be pushing testosterone supplements, power washers, and support for a specific middle east ethnostate whose name I will omit.

This article leaves out far too much information on the situations. he flux image shown says basically nothing but location of failed reads. It reminds me of trying to read bad floppies with the Greaseweazle software and it was unable to re-read bad areas. This and incredibly bad floppies [1] is what triggered me to build my own host software RecoveryWhiskers [2].
I want to re-iterate why archiving and archiving floppies is important: Public archives are disappearing from the internet. This is an alarming trend.
But a lot of software is not archived or filed properly. What we need is more people doing library work: Fill software libraries with software, fill out metadata, briefly describe what it does and collect all versions you find.
Interestingly floppies are less of a time critical issue: If stored properly, 30-40 year old floppies are still good. There are a few main causes of bad floppies:
Dirt & nicotine residues: Sometimes there is so much dirt on a floppy that reading it would act as an abrasive medium one you apply pressure onto the head.
Mold & moisture exposure: Most kind of molds sits on top of magnetic medium where it found some moisture. If they sit...
