Recharge Your USB Flash Drive Today or Say Goodbye to the Files Tomorrow

I know, I know. The title will inevitably raise some eyebrows. Rest assured, though, by the end of this brief post it will make perfect sense.

A couple months ago I sat down to sort out my USB thumb drive collection. I have 10 of those used either to move large files between distant machines, as OS installation and recovery media, and to actually store some non-critical data. While going through the inventory I eventually plugged in the USB stick I brought back from my Summer 2018 trip to Japan. The last time I used it was around September 2018, when I transfered some video clips from the PlayStation 4 to study while building my Dynamic Sloshing Liquid Rig.

Which means the drive was left unused for 3 years.

Imagine my surprise when I found out that two out of three short in-game video clips were corrupted. The first clip wouldn't even copy over to the PC, while the other one took its sweet time and eventually, after about 30 minutes (for a 100 MB file), succeeded in getting copied to the HDD.

Overwhelmed by avid curiosity I immediately fired up the video player...

What you see here is the result of physical data corruption. While such graphic and "movie-like" damage is, funny enough, quite fitting to the overall presentation of Horizon: Zero Dawn — a game about hunting mechanical dinosaurs in a post-apocalyptic world, — this incident begs the question...

What Happened?

To answer it, let's briefly recall how a Flash Drive actually works.
