Wow. I was just responding to this message, and also transferring 29g-ish from my HDD to the Shareport drive. It was about half-way complete, and I got nailed with the first blue-screen I have ever seen on this computer. (Win7). I got a partial glimpse of the error and I saw something about a problem with MDL... I'll have to dig in my error logs to see if I can find more information.
But yea, I got a blue-screen too, almost shocked me too much to focus on the error screen and catch any information at all.
Using 1.33NA firmware and Shareport Utility 1.1.0. R1 (the versions found available on the DIR-655 product page)
