A few days ago, my Time Capsule started flashing amber and it said "disk is failing" in Airport Utility. My Time Capsule is working fine for wireless internet, backups, and restores. In other words, there are no noticeable problems other than the flashing amber light and the message in Airport Utility. I decided to click "ignore" so that it would go back to normal, and everything is still working fine. What should I do about this? Should I pretend it never happened and keep using it until it breaks? Or should I exchange it now? It's still under the 1 year warranty, but I don't want to go through the hassle unless I have to. If I end up having to take it in, how would I delete everything on my Time Capsule?
