I managed to put this only on one USB stick without problems.
Other 2 I get an write error at around 90% or so and now I can only see in windows the 8mb partition .
One is a usb 3.0 stick and one random.
The one that works is 3.0 also but they are all different brands

Any way to format these sticks again ? In win i can see the other part of the stick in disk manager but i have it as unalocated space if I format it .

Thanks!
