Hey Juxt! felt like letting you know that if you use a thumb drive as external storage on your Wii U, you should consider upgrading to an HDD or SSD (whatever works best for you). Thumb drives can fail on you randomly causing data loss, so it's better to be safer than sorry.

I posted this because last month my thumb drive failed and I lost 90% of my Wii U data. I don't want others to experience what I had to go through. If a thumb drive is all you can afford at the moment, it works as a temporary solution, but do not make it permanent.
my wii did that too. now i have to buy another one for my laptop
