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.

I can't tell for sure if it caused any damage, but it doesn't seem so. I did restart the TimeCapsule as suggested in the Apple Technote and it came up fine; I haven't investigated the issue more since though. I might dive into it again once I have a bit more time, perhaps there is a way to access some logs on the device?
