Check your thumb drive with Check Flash

John C. Dvorak: “I’m gonna recommend a thing called Check Flash.”

“When you buy a new thumbdrive, it will check to see if your terrabyte drive really contains anything near a terrabyte. Do this at the beginning before you use the drive, because it will erase everything.”

“So when you get a bad drive, like these phoney drives I got from Ali Express, you can check if it’s legit.”
