I have Windows 7 and could not get my new Samsung EVO Class 10; 64Gb U3 to format in the FAT32. Instead it would only format in FATex.
As a matter of fact, Windows told me it couldn't format the Disc at all when I initially put my mini memory card directly into my Anchor memory card reader. I then put my memory card into the adaptor that came with my Samsung card and then inserted that into my computer's USB port. It was only then that my comp would recognize the card, but would only format it in FATex.
Desperate, I googled the problem which then led me to my old standby, Dashcamtalk, and landed on this thread.
Not surprisingly, the experts here had the solution. I downloaded the program mentioned in the first post (as endorsed by Street Guardian) and the card formatted perfectly.
Thank you all for your help. Now all I need to do is ad my latest firmware update to the newly formatted card and install it in my older Street Guardian.
