Why is that neither simple copy operation, nor even backup with specialized software ((such as WD Backup Anywhere I'm using with my new DW My Book Studio Edition II drive), are able to copy the c:\\my documents\sony media libraries\my-name.medialib type of files? Some strange access/ownership rights setting, but what for and what is the work-around?
Such errors usually happen when a file is currently in use by its appropriate application, but of course this is not the case here...
