I've only used Sandisk as USB Flash Drives.
Never had a fail with Samsung evo+ micro SDXC. I use them in USB adapters & in plain SD adapters. I also buy them from reputable outlets.
The Wii doesn't detect the sd card at all? Make sure the lock slider on the sd card adapter is in the unlocked position.
As for brand, you might want to make sure it's not a counterfeit one, check it with h2testw to make sure it isn't.
Thanks, CoolMe.
I always hated updates & figured they added with the cause. Updates are now fully disabled ! Freedom at last !!
Just have to avoid Chrome ad days. Google - You SUCK !!
My main issues seem to have emanated from a faulty USB port...
Cruisn on the Wii is one of my personal examples of that, it's considered one of the worst games of all time, I loved it and completed it several times.
