On 11th October we held our first JHOVE online hack day. Our aim was to catalogue error messages produced by JHOVE to get a better understanding of their meaning and potential preservation impact. Background: organising an online hack day We have been considering running online hackathons because attending face-to-face events has become more difficult as […]

BACKGROUND Nearly two and a half years ago, I started an effort for Apache Tika™ to help improve its robustness via TIKA-1302.  Apache Tika™ is an umbrella/wrapper project that “detects and extracts metadata and text from over a thousand different file types (such as PPT, XLS, and PDF).” I documented some of the early work […]

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 […]
