Hi, I have a Iomega Prestige 2TB External drive. I've always used it with my UBUNTU computer with no problems. I plugged in into my G4 Powerbook yesterday and it wouldn't let me put files from my mac there because I didn't have "permission". Fine with me, but when I plugged it back in to my UBUNTU computer I can't see any of the folders or files anymore. I plugged it back into my mac and I can see everything fine. Any idea how to make them visible on my UBUNTU computer?
