While copying a set of files and applications from internal hard drive to external USB Zevo pool, I noticed two application bundles on the destination drive were marked as corrupt (Get Info showed "damaged or incomplete' and icon was "do not pass" sign). I deleted these two apps and re-copied them (did a drag and drop in both instances). Again both were marked bad - with no error messages or indications. The apps on the source drive are fine and launch ok.
This is a worry as I have moved a number of critical files and apps to a 1TB Firewire volume.
Suggestions?
