What to do when your usb pen drive does not work?
Here's solution I've found, for your consideration.
1. Unplug your usb pen drive from its current port.
After 2 or 3 seconds after that, insert it back. If your computer or your laptop still does not recognize your usb pen drive, press restart button. Maybe your usb port driver doest not fully loads up during the last time you turn on your computer.
2. Try inserting your usb pen drive into the other computer.
Maybe your friend's computer or your sister's laptop. If your pen drive works in their computer other than your computer, than means your computer must have a problem. Maybe you need to re-install usb port drive, or maybe the usb drive is missing.
3. Accept the mistake, buy a new usb pen drive.
If your pen drive still does not work even you've tried two steps above, means that your pen drive is fully damaged and cant read or write any data at all. When you check the status in properties, it will show you FULL sign (all in blue, not pink). It maybe damaged by nearby magnets, somebody fragmented it without your consent, maybe you've formatted the pen drive over an dover again.
