I bought one of these, and now regret my purchase. It worked fine for about six months, but now, despite my having followed all of HP's guidelines re. performance and maintenance, I'm lucky to be able to create a CD 20% of the time. The little green light on the unit flashes and flashes, then suddenly stops... the status bar reaches 98%... and just sits there. Time to reboot, throw out the CD and try again!
