It may have other partitions on it. you should have single partitioned, fat32 formatted and >16Gb usb stick. Size depends on amount of data we backup, so you may have 8Gb and that is ok. please connect USB stick to PS and open Drive Management to confirm partitions state.What if I have a usb stick that the LS can see when I goto import/export points but when i goto migrate it has a message "No usb stick detected!" It is formatted with Fat32 and doesn't have an active partition. I do have an option to make an active partition so I would think it doesn't have one.
