I have a Windows 7 Starter netbook and plugging in some Toshiba DVDRW USB drive and it just worked fine.
However I did install my own choice of recording software after letting the netbook create the restore DVDs.

I have a netbook and I want to make the back up with an external dvd burner and it is not recognized by the windows 7 starter.
