I have tried 3 different thumbdrives and every time the copy begins OK but slows down to almost nothing after a few GB, and starts indicating errors in the files. Finally I give up.
As I said above, a friend told me that memory chips are just not good for this type of large operation and that I should stick to hard drives. I am hoping that someone can give me a solution. I am feeding Cabasse speakers that have a micro usb input that is only for a hard drive or a thumb drive and would like to clean up the setup.
