Compare two identically sized files for byte by byte differences, e.g. floppy disk extracts
Output a PNG visualization of two byte-streams.
A rudimentary tool to begin with to compare two identically sized streams. Lots of scope for improvement if it proves to be useful.
KEY: Purple is where the disk images are identical, yellow is where there is a difference.
- We will first notice a checksum difference,
- But how different are they?
If there are no legacy disk images/checksums to compare against, then we can still understand the volility of the disk today. Take two extracts, with a small amount of time between doing so and then compare them.
I believe this is the equivalent to be hard of seeing/hearing.
The reader will do its best to understand, but the signal is analogue so its understanding is on a spectrum. We're not expecting binary results from a volatile analog medium.
Is an ability to make a statement about the health of the disk. To make a disclaimer about data and record integrity. The user of the archive has to be able to fill in the gaps without more questions being raised - provenance.
