Has the Disk Utility repair caused any damage to your Time Capsule? Have you found out any way to figure this out?
You can pull the HDD out and then do a check with Disk Utility of you have a HDD bay. But then again that would void the warranty on your Time Capsule if it is under warranty.
Thanks for the comment viggio! Never considered it as a failure of Time Machine but I sure think it is something that can be prevented by Time Machine by just running a integrity check on the disk drive (even as optional feature) prior to doing a backup. After all its a backup that you rely on :)
