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 […]

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 […]

Over the last 30 years many hardware concepts came out of use. Parallel data cables are not common any more. They got superseded by fast serial connections like e.g. SATA for traditional parallel IDE. One of the longest lasting standards, the 34 pin floppy controller connector, came out of use too. Fortunately, not too long […]

A while ago the digital preservation team of the professorship in communication systems got involved in Digital Archaeology and Forensics of some old floppy disks of unknown origin. It was a cooperation with The Archives NZ being asked to identify the content of 5.25” disks. The hardware part – reading the disks and producing images […]

Note: This post includes hexadecimal numbering to represent byte values. Where appropriate hex values are preceded with ‘0x’, e.g. 0xA1B2. Last week was notably busy from a PRONOM contribution perspective so I thought I would share some words about the work, in the spirit of Ross Spencer’s five principles for better information sharing for file format signature development. You can […]

At Archives New Zealand we were finding ‘WAVE’ files becoming a bottleneck of one of our ingest processes. The result initially looked odd to me where I had thought I had understood in the past that file format identification would not take longer to divine than a checksum. My rationale being that to identify a […]
