As a specialist of “You did forgot to umount your USB Stick” in my virtual machine / local Laptop I always end up with “your USB drive was not unmounted properly”.
- Here is what I do to fix the USB Stick:
- # lsusb ## need to check if the USB Stick is recognized
- # df -h ## only one out of many options to check if and where the USB Stick is mounted
- # fsck -Va /dev/
- wait and relax – than DO NOT FORGET TO umount YOUR STICK
