There should be an IT Driving Test
Not quite the same but in a similar vein.
I got a call from a Friend early one New Year's Eve.
Rather than the expected drinking session I'd imagined, he was in a panic as he was DJing that evening and had lost his music.
It transpired that after hours of creating playlists his ageing slab was low on storage so he deleted the MP3s to save space since he had his playlists, right?
Not wanting him to miss the gig,a fair few beer tokens and Ladies phone numbers I sent him t the bar while I booted a recovery stick.
Sure enough, said MP3s started to return from the abyss, along with some assorted trash and some "interesting" videos.
Convinced I had put them there he started to protest.
A quick call to his significant other and the culprit was identified.
We recovered all of the music plus 'er Indoors' deleted stash of entertaining videos.
