New to WD products. I am now in this situation - i have a 4tb my book fully loaded with films etc. It is formated in exFat (yes, exFAT not FAT 32 etc). I have win7. I also now have a 4tb my cloud connected to my home network. i use powerline adaptors and am waiting on a gigabit router. via usb connection, my book is not recognised by my cloud due to format. i can file transfer from laptop to my cloud, but i’ll be grey before that completes. is there a better solution for me?
