This is a relatively long post, so to summarise before delving into the details: We’re exploring Wikidata, the (relatively new) Wikipedia for data, as a knowledge base for digital preservation information and would appreciate feedback and involvement. At Yale University Library we are beginning a new programme of work (with funding from both CLIR and […]

Finally, we have confirmation for the original hardware, an HP9845 with an external floppy drive, the HP9895A Disk Drive attached to it. The disks have 77 tracks, or cylinders, and contain 30 sectors with an interleaving factor of 7. The machine was marketed for scientific purposes and was widely used in the university’s medical centre […]

Becoming more confident in the low-level encoding, it is time to look at the reproduction of actual bit streams. Our current knowledge, together with the directory listing, strongly suggests an HP system of the 1980s.  The call for input brought up some more information on possible disk formats. A colleague (in another city) who worked […]

The experiments and floppy disk imaging in Berlin left us pretty optimistic, that our hardware setup for the recovery task, especially the Mitsubishi floppy drive is working properly. We got a stream image of every disk that we can analyze further. Of course we hoped that we would get results by just running the Kryoflux […]

The National Library of New Zealand is looking for an experienced Digital Preservation Web Engineer to lead its web archiving programme. This might feel like job recruitment post, but we’re seeing at as rare chance to talk about how we think about our ongoing digital preservation program, and what happens when we identify a gap […]

The story so far An 8″ Floppy Disk Challenge Digital Obsolescence: Reproducing Floppy Data Cables Spinning up the first 8″ disk Running more informed experiments in the 8″ world Getting desperate: Down to the Physical Layer After confirming as well as we could that our hardware setup of the 8” drive and the adapters was […]

After we found out about the fdrawcmd and the characteristics of the Nashua and its track 0, we hoped to reproduce it on the relevant disks. Unfortunately no success here. We had to rule out possible problems like: The disks were not formatted at all (because of being backup disks – at least some labels […]

One of the major challenges is the lack of experience with the 8” drives and floppies. Thus, a trial and error was the approach we used. The knowledge needs to be unearthed step-by-step hoping to find the relevant bits and pieces to get the stuff working in the intended way.  In parallel we tried to […]

Inspired by Jenny Micham’s blog post about developing her first file format signature, I thought it would be fun to take a crack at creating one myself. I previously dipped my toe into the world of contributing to PRONOM by looking at a few mis-identifications and multi-identifications, but I had yet to create a file […]

Proceeding with our 8″ recovery project: After a short while the 24V power supply and the cable adapter board arrived from the U.S. Both have power requirements and fit traditional PC power cable sockets. To actually connect the 8” drive without external power supplies the machine should contain a 3.5” floppy disk power connector and […]
