Reformatted the SD card at FAT and it worked; thanks for the help!

I dragged that exact folder to both types of media. I'm on a Mac; does the format of the media matter?

Downloaded the firmware update and copied onto both a USB drive and an SD card. Tried to update my NEX 4000, first with USB, then with SD. Both times, I get an error message that says it has "trouble reading, make sure update files are on root level and try again." The files are the only files on either device. Suggestions? Am I doing something wrong?
