Hello, i have a Lexar usb flash drive 64gb and i installed mem test 95 on it to run some tests. At the time i didnt have any other option to put it on so its my fault but now i can only use 59mb of this usb flash drive even after i formatted it. Is there anyway to get back the total 64gb of space or am i doomed to only have 59mb on this drive???!?!?!
