Question :
When looking at the space left at My Book the scale is now showing up in red… when before it was in green. I am assuming this means that it is close to being full. Is this true or does it mean I have a problem with My Book?
Wich My Book drive you have and what operating system?
If you are using Windows Vista or 7 this means that the drive is getting low on available space
Not sure if this will work for you but you could run disk clean up or you could also delete data you dont need manually
