I'm moving my capture scratch files onto my external (i didn't have it when i imported), and half way through the 24 GB folder it stops with this message: The Finder cannot complete the operation because some data in file "Untitled6-av" could not be read or written. (Error code- 36) This has happened with various files, i'm starting to lose my patience. I have tried to open the file, in quicktime, but it is not recognized. When trying to open the file in Final Cut Pro, it crashes. Any help appreciated, Rich.
