Your computer can’t read a floppy disk – so how do we save the history they hold?
Floppy disks and CD-ROMs are important holders of our archives, but reading them on modern computers is a problem.
Archives are often thought of as boxes of physical documents, photos, and materials stored away in a secure location. However, in the modern era, a significant portion of our history is now stored digitally on outdated platforms such as floppy disks and CD-ROMs. As computer technology advances rapidly, older hardware and software become obsolete, making it difficult for contemporary computers to access data stored on these older formats.
This digital preservation issue threatens to lose important cultural heritage, personal narratives, and important records from the 1980s, 1990s, and 2000s.
The Royal Historical Society of Victoria recently collaborated with a research team to help preserve their digital holdings. This collaboration aimed to rescue data from obsolete storage media such as CD-ROMs, floppy disks, and Zip disks that are increasingly hard to access due to technological advancements. The team employed a three-step process to complete the digital preservation workflow: creating a "disk image," analyzing the content, and storing the new content.
To create a disk image, vintage and restored hardware drives are used to read the various outdated storage media. The resulting bit-perfect copy captures the entire contents of the disk, including hidden or unused sections. This process helps to rescue valuable data that would otherwise be lost. For example, floppy disks present unique challenges as modern computers lack the necessary drives to access them.
However, with the help of specialized controllers, such as Greaseweazle and Applesauce, the team was able to successfully read and preserve these disks.
Upon examining the data from the Royal Historical Society of Victoria, the team discovered a diverse range of materials, including genealogical files, Word documents, oral history recordings, and photographs of engineering projects. These materials have the potential to provide valuable insights into the lives of individuals and the development of technology in the past.
For instance, a local library staff member gained access to recordings of the 1991 Australian chamber opera Seduction of a General, which could be crucial for future research.
The success of this conservation effort was further demonstrated by a member who brought six 3.5" floppy disks containing data from a discontinued genealogical program from 1996. The imaging process allowed the team to recover and re-access this data, which had been stored on both floppy disks and the outdated software. The resulting digital files could then be converted into open file formats, ensuring they remain accessible for future use.
While this rescue session provided a significant step in preserving at-risk content, the long-term viability of these digital archives remains uncertain. Smaller organizations and individuals often hold historically significant content that is not preserved through formal digital preservation systems. Collaborative efforts, such as those undertaken by the Royal Historical Society of Victoria, are crucial in alerting custodians to the importance of data preservation and making it possible to access these materials despite the challenges of digital obsolescence.
