Does anyone here know how to remove the hidden folders Mac OS X creates on thumbdrives, namely the .trashes folder and Spotlight folder? I'm trying to update my Japanese TV using a flashdrive, but it's complaining about the software update not being the only thing on the drive. I've reformatted twice and the only thing other than the software update file are those folder OS X creates automatically. I don't have a Windows machine to connect to, so what other ways are there to delete those hidden, system folders?
