I have a WD external My Book hard drive which has my back up on it.
I powered it on, plugged it in to my laptop and it showed up in device manager but not in windows explorer. The laptop is running windows 7 64bit.
I then tried it on my desktop computer which is running XP but it was exactly the same .
The option to Safely Remove Hardware is available on both the laptop and Desktop.
How can I get access to the files on it ?
