I just received a SanDiak Ultra USB 3.0 Flash Drive 32 GB. I have updated the security s/w and backed up several folders in My Documents as well as my Outlook PST file. I don’t have any music files on my device: Toshiba C55-A. Is the Synchronize menu selecion used to keep files current on the SD? This menu selection is not enabled - how do I enable this?
