I got my Extreme USB3.0 flash drive 64GB and all works perfectly on my OS in MacBook.
Whenever I insert the drive to Windows computer it is not recognized… and want me to format it for max size 200MB. I attached some print screens from Mac and Win
On the Windows machine disconnect any USB device, and insert the USB flash drive, then open the “sd card formatter”, click on “Option” and select “Format size Adjustment: ON”, and proceeds formatting.
The USB flash drive will be formatted in exFAT file system, compatible with Windows and Mac.
