My 2 TB, 3rd generation Time Capsule just started making a beep-like noise today. I bought it about 30 months ago.
It beeps only when I do some disk access, e.g. when I access the filesystem remotely. Using it as a wifi router does not make it do any noises.
What should it be?
Edit: after 2 weeks with my Time Capsule beeping on every disk access, suddendly after a restart it just stoped. I restarted it before, but it had no effect, I have no ideia why it worked this last time.
