A file is a file is a file. If the flash drive is not defective, it will make exact copies of your RAW files. The internal arrangement of a file does not matter. There will be no loss. That is the sole beauty of the digital realm, perfect copies, never possible in the analog world. Digital files are just lists of the numbers one and zero which the computer interprets from various data, including the extension of the filename, that are simply copied from one place to another.
