Quick List: How to Do a USB Drive Health Check Visually
You should try to make a USB health check a habit, especially the visual check. Do it with the USB drives you most frequently use. Performing a visual USB stick health check is straightforward. Here is what to do:

These connection points are delicate, and if they stop functioning, they can cause significant damage. For instance, they can short-circuit your USB drive, make it inoperable, and fry the memory;
- ✅Check the indicator lights – indicator lights often turn on when you connect the USB drive to the computer. Make sure they light up every time you use your drive.
