I am having a problem with my new Time Capsule. Everything was fine for the first two days. Then last night it wouldn't connect and came up Failed every time. I was able to go back in time and see all my stuff since the last backup but couldn't add to it. It did it the third time I tried but very slowly. This morning I tried it and I am now getting these two error messages: "The backup volume is read only. To select a different volume, open System Preferences and choose Time Machine." I set it up and have been able to write for the last few days until last night. The other error says something like "The disk "Brendan Chase's back up of MacBook Air is not repairable by this computer. It is being made available to you with limited functionallity. You must back up your data....etc" What is going on and why was it fine and then not fine?
