I just upgraded my pc, and have 5 HDs in there now. Unfortunately, to get it all in there, I had to move the DVD drive with the ERT disc off IDE and onto a USB interface. That wouldn't be a problem, except for the fact that Starforce refuses to recognize the disc now. I see the drive spin up and it seems to be seeking, but then Starforce says it's not there. Googling my symptoms, I see that it's a Starforce problem. Either they haven't yet supported USB optical drives, or refuse to.
Others complain about Starforce for different reasons, but this is a truly major problem. There is no video game that I play as much as ERT, in fact, it's pretty much all I play, and now I can't do so with ease.
Starforce does indeed suck.
