While reading some miscellaneous information on the net, I came across this line:
A project for another day will be acquiring lots of refurb microSD cards and collecting interesting data off of them.
Given some spare money, I might go to some shops and kiosks that sell second hand memory cards and see if I can get some interesting data, in the same spirit of the original poster. Will use some recovery tools in Linux to do the job.
But not today, there’s a pile of schoolwork waiting for me.
