If you simply remove the USB stick after use, data may be lost. THE STICK BECOMES UNUSABLE!
Therefore, please first "EjectLink" the USB stick and do not simply pull it out. To do this, open Windows Explorer and right-click on the name of the USB stick and select "EJECT".
Or click on the icon of the USB stick in the taskbar at the bottom right and select "EJECT HARDWARE SECURELY".
