Here is what i needed to do for my drive "320GB HD", the last command is just for clean up
Open Terminal and type these commands carefully with the spaces & change 320GB HD to the name of your drive.
sudo chflags 0 "/volumes/320GB HD"
sudo chown root "/volumes/320GB HD"
sudo chmod 1775 "/volumes/320GB HD"
That said, these should be sufficient to do the job:
sudo chflags 0 "/Volumes/320GB HD"
sudo chmod a+rx "/Volumes/320GB HD"
Or if you're careful, BatchMod, it's much better/easier than the Finder for recursive Permission changes, but careful, it's powerful...
¡You're my undisputed hero!. I'd like to hug you and kiss you, I really thought I was lost there forever, and than there turns up a real computer wizard like you with the terminal commands!!! It's just lovely. I'll be able to sleep better than ever this night. I'd be honored if I could help you out someday, apparently with something else than computers. ;-) You just gained a friend in Europe, Norway - Spain - Sweden. Many thanks again, I really ow you one!
