The ability of the computer to backup when the PC is idle, does not work at all. At startup, when WD My Book is connected, other programs like p.e. Windows Media Player do not react at all no. And it takes too much time before those programs do respond. The same phenomenon occurs when WD my book is starting when the user is active on his PC
Suggestion: Allow at startup of the PC that users decide whether they want to use my book. The choice must be available during the entire session of the PC. During the session of the PC users must be able to switch-off WD my book by software.
