Here are the problems I was seeing

And here's how I fixed it

aboyd-laptop:TimeCapsuleAaronLaptop aaronyo$ hdiutil detach /dev/disk2
"disk2" unmounted.
"disk2" ejected.

Stellar Volume Repair is OS X based utility that repairs Invalid B-tree node size error on Mac OS X disk. For boot disk, it creates a boot dvd and repair the corrupt hard drive in bootable environment. I have been using this software for last few months and it saved my disk from a major logical disaster. I invite you to give it a shot. Link - http://www.stellarinfo.com/mac-software/volume-repair.php

Thanks a lot for the tips, i had a similar problem and fixed it using ur "how I fixed it" !

This worked except that the last filesystem check didn't start automatically after the 'hdiutil attach -nomount -readwrite my.sparsebundle' command, as implied by your post. Instead it was necessary to re-run the 'fsck_hfs -drfy /dev/disk2s2' command.
