First step of troubleshooting: If it worked properly for a considerable amount of time, what happened to make it malfunction? What changed? I know a guy who used to beta test mac products. He had an office crammed with hardware and software that Apple sent him to test and test he did and problems he had. And yet, we had a whole plant full of Macintoshes that were trouble free. The only mac he had in his office that he could count on to work properly was the one he did NO beta testing on. I have no problems with my four FAPs connected to 700s. And if someone offered to make me a beta tester, I would refuse the offer. Too much like work. I have had six 100s since last November and hooked up an FAP to five of them. I still have the one I didn't hook up an eSATA to, my son uses it and says he has no problems with it. I am sorely tempted to hook up an FAP to it, but he doesn't screw around with my stuff and I don't screw around with his stuff. But I am sorely tempted. Oh, the other 5 100s failed for various reasons, some that could not be related to an eSATA.
