I had a less technical savvy coworker putting together a raspi for something, emulation I think. And he was notoriously cheap, he told me he got a micro SD from China for a suspiciously low price.

Well during this endeavor, he would keep asking me about random errors he was seeing. And I kept saying bro it is that cheap SD card you bought. He wouldn’t hear it.

Eventually, he tried out another SD card and sure enough, no more weird errors.
