I had a folder created on one machine which crash. Plug in My Book on my another machine, it was not there any more. I could save more stuff from the new machine but what I had from the broken machine was not found. I could set security to everbody to MyBook as an external drive but the old folder was not visible. When I set security, I saw it also set to the old folder but it still has access blocked.
Thanks for your help in advance.
