Files on MyBook "changed" when opening with MacBook

Hello
I have used my MyBook for many years. I recently changed from PC to MacBook. Now I needed some files that I backed-up a year ago and the following has happened when I connect MyBook to the MacBook:

  • some files are the same: GREAT
  • fore some files however, the file image changed to a black icon, the size decreased to 0KB and the description changed from ‘folder’ to ‘UNIX EXECUTABLE FILE’. When I click it some little program opens and stops immediately.
    Has anybody a good tip what I can do to recover this info? It would be a great lost if I could not retrieve anymore
    Thanks! Armand

Hello,

What type of files are you having the issue with? Make sure that those files are not direct access files, or installation files.
