Ok,
I think Mac is creating hidden files and folders in disks/folders it opens. Usually, these are hidden simply by the old UNIX trick consisting of a name begining with a dot (.)
Under a Mac, one cannot usually see these, unless opening a UNIX terminal, and browsing in shell (cd XXX, cd .., ls -lsf for full listing of files and folders, hidden also shown, rm or mv these .names, and it should clear out problems, no?
No one else here with Mac - cowon experience?
Thanks alot
