Stephen Hawking left a hidden treasure that has just been discovered. The problem is that it is in the form of floppy disks

The Cambridge University Library houses several historical treasures including letters from Isaac Newton and notebooks from Charles Darwin. Now they will take care also of manage 113 boxes with documents and memories of the physical Stephen Hawkingbut in those boxes they also found a surprise turned into a challenge: floppy disks. Lots of them.

Computer pioneer. The famous physicist was an early user of those first computers in which data was stored on floppy disks. When he suffered from ALS this was a very important resource to be able to communicate and work, and now those disks that have just been discovered could contain all kinds of revealing data about Hawking’s life and work.

Future Nostalgia. That’s what it’s called the project of the University of Cambridge and its library that precisely tries to safeguard all that information that in the past ended up being stored on floppy disks. Recovering such data is not easy when so much time has passed, and this project tries to educate about the best ways to preserve said information and transfer or recover it from those floppy disks.

A format with an expiration date. Although one would think that floppy disks are a more secure way to store data than paper and ink, this physical medium also has clear disadvantages. The iron oxide covering the thin layer of plastic can degrade and lose its magnetic capabilities, meaning data could be lost forever.

Each floppy disk is a world. With old books there are not too many problems when it comes to retrieving the information: you open them and read them (if you understand the language, of course). With floppy disks you need the hardware to be able to read them—a compatible disk drive—and also figure out how they are formatted. Leontien Talboom, responsible for this project, explained How to also clean those floppy disks was complex and there were various methods that they were exploring. These included the use of hand soap or isopropyl alcohol.

Hawking used both a PC and a Mac. The disks arrived at the project in two batches. The first, with five and a quarter (5.25 inch) disks formatted on an MS-DOS based PC. The second, with three and a half disks, somewhat more recent and that were still used on an old Mac. According to Talboom, they are mainly talks that Hawking gave: “from a technical point of view they are really interesting because his talks were so big that he had to divide them into several floppy disks.”

I wrote to speak. Hawking’s illness left him unable to speak for himself, so for years he used various voice synthesizers to express his ideas. Precisely for this reason he wrote so much on the computer and saved those documents on disk: this allowed him to use them later so that his synthesized voice could read said documents.

Different discs, different readers. Although 5.25″ and especially 3.5″ discs were the most widespread, other formats were also seen such as eight inch discs which for example were used in the Churchill Archives Centre. Chris Knowles, one of the Future Nostalgia participants, explained how he bought a player for these discs on eBay. “It was a miracle that it worked,” but that allowed him to recover the information from those disks.

Forgotten formats. They have also received some three-inch floppy disks, a much less widespread and peculiar format that had some success in the United Kingdom before the 3.5″ format was clearly imposed. To recover them, they ended up using an old reader manufactured by Amstrad that they had to modify to bring it back to life.

And then there’s the software problem.. The information recovered from these disks can also pose another challenge: that it was created with software that was abandoned and even ended up disappearing. Some disks, for example, had documents written with a missing word processor called Diamond Word. That’s where a kind of “translation” comes into play to convert those files into something readable in the current era.

Safeguarding our past. This work demonstrates how critical it is to try to protect and recover information from these old formats. Many of those floppy disks are 40 or 50 years old, and as Knowles says, “old emails and work calendars may not look like historical documents. They might seem banal. But they’re what Newton’s or Darwin’s letters would have looked like 200 years ago. Now they are fascinating documents that open a window to the past.”
