I have a 300Gb SATA drive linked via USB to an Aiport Extreme n. I've been copying media across to it via wireless from a MacBook, creating and organising folders and moving the media into them. Trouble I'm having is that when I open Folder A to check the media has moved across then come out, then click on Folder B, B suddenly assumes Folder A's name and contents and I can no longer find Folder B or its contents..... I'm new to OSX, but I can't think why this would happen under any circumstance. Probably not a very good description of the problem, but in a nutshell that's about it. At work just now, so can't give any screen grabs, will post from home later today.
