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 They got superseded by fast serial connections like e.g. SATA for traditional parallel IDE.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 […]

Jenny Mitcham, Digital Archivist at the University of York started a nice snowball rolling last week when she asked “Research data – what does it really look like?” Paul Young at the National Archives, UK, was one of those to respond, to show that perhaps the snowball had been generating momentum for a number of […]

As promised yesterday this is the follow up blog to the refactor of my original DROID SQLite Analysis work. The new version now allows you to produce reports from the format identification tool Siegfried. In this blog I wanted to talk about a small number of other details that can be a bit harder to […]

With the release of the latest Siegfried there was added motivation for me to provide an analysis output for the format identification tool. With ‘double the magic’ there was a lot more for us to explore as analysts, and fingers crossed this release (a refactor) of my SQLite based analysis tool will help with that exploration.
