I’m having the same issue…It’s gotten extremely difficult to access the drive. It just keeps flashing but no window no driver installation NOTHING. I too have used all my usb ports restarted and read what DID come with the product, because not even a user’s manual was packaged with it…and for the amount of money that was spent YOU’D THINK it wouldn’t be so difficult to install and use. Extremely dissappointed…about to get a refund.
