I suspect that they're "Live File System" disks, which are produced by default when someone running Windows XP or later sticks a disk in their drive and writes to it: <https://discussions.apple.com/thread/1086518?start=0&tstart=0> You may be able to close these disks on your wife's computer. Also ask the folks producing these disks to make them in the 'Master' format or 'Close them' (I think that's the option.) -- Bruce Johnson University of Arizona College of Pharmacy Information Technology Group Institutions do not have opinions, merely customs -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
