I woke my new BigAl from its overnight sleep this morning, and noticed something new... when it was first cycling back to wakefulness, the superdrive made a grinding noise, as though it were trying to mount a CD. I can't be positive, but I'm pretty sure it never did this before. I disconnected everything from it and powered down, then restarted, and it will still doing the same thing. Odd. It's not serious, it's just annoying to have what was previously a silent wake-up now be noisy. Anyone seen this happen before?
