Hope the sandisk is a genuine one, I was told there are some fake flash drive out there that they use 4gb or 8gb drives to use a special program to fool the operating system that is 16 or 32gb. but when you reach to the capacity it shows the true capacity. hope this is not your case.
I have a problem with my 2 brand new 16gb sandisk, I can’t install u3 launchpad to it. it say the drive I have is not a sandisk smart drive. I purchase these drive for use with u3 launchpad and it can’t be installed.
best wishes
