Query: Same frustration...

I've had my SG300 for 3 years now, and it inexplicably stops on its own (you can hear an internal shutoff click) and, ultimately, freezes, and all data is lost. It failed from the first time used. If I attend to it by not letting any time lapse, I'm ok, but that's hardly reliable! I've initialized countless times over the years. I'm on a Mac. The software that came with it was for a PC. In case it's my mistake (not knowing how to use it) I've talked to countless people (PC/Mac) and researched on the web and no one has a solution, but I AM reading about similar complaints. I use it ONLY as my secondary backup, which I keep offsite. My firewire LaCie Porsche, on the other hand, works flawlessly! I don't take this SG seriously.
