How-to: Diagnose an SD Card that’s stopped working

SD Memory Card from Open ImagebankIt never ceases to amaze me how resilient is the humble SD card. They take heat, cold, damp, weight, an infeasible amount of weight, bending and mistreatment.

The trouble is, any type of file can be attached to an email, and whilst most mail servers run some sort of virus scanning and either remove or ‘quarantine’ suspicious emails, anti-virus software isn’t perfect.
