Just purchased a Go Essential 6" and inserted a 16gb SD card to transfer data to and from MyDrive on the MacBook Pro. I managed to copy across two files from MyRoutes from the device using the the SD card. However, I deleted the folders/files on the SD card and thereafter unable to transfer any files from the device as it states: 'Memory Card Un-recongized' using the memory card. Files will transfer using the USB from MyDrive to the device but the SD Card Un-recongized. I tried formatting the SD Card from the device and the MacBook and even using the 'SD Memory Card Formatter'. Even tried the drum reboot a couple of times but still no joy... Any advice would be grateful, cheers..
