Time Capsule is “preparing” forever, diagnostics and also hangs


I have two different problems now. First, the Time Capsule at work is "preparing":http://discussions.apple.com/thread.jspa?threadID=1606417&tstart=0 forever. No one really has a resolution to this. I've run it for 24 hours and it never stops preparing. I really don't want to lose my backups, but not sure what to do. Maybe take it home over the weekend forever.

Some folks recommend limiting the files you backup (the point is a whole disk recovery!) or turning off Spotlight. I don't know...

You can check the "system log":http://discussions.apple.com/thread.jspa?messageID=7554509 by going to:

# /Applications/Utilities/Console which is a confusing application.
# On the left side, there are many Log files and many different entries. Click on _All Messages_
# You want to search for the backup process called _backupd_ by going to the search box at the upper right and typing _backupd_ and pressing enter

Here is an example of a good backup log:

The other issue which just happened is that my Time Capsule seems to hang. The light stays green but it goes offline line like it is crashed. No internet and it disappears as a hard disk. Seems like a hard crash. Hard diagnose but I was doing a big spotlight search of it, so it looks like some bug in the filesystem is hard crashing it.

The "folklore":http://discussions.apple.com/message.jspa?messageID=6886156 is you need to fix permissions and repair the disk before you do the backup and use a wired Ethernet connection as that seems faster.
