Fixing corrupt sparsebundle

I've had my Time Capsule for close to 6 months, and now when Time Machine tries to backup, it gives me an error message saying that verifcation failed and I need to create a new backup. I don't want to lose 6 months worth of backups. I have found several sites that provide detailed procedures for repairing the sparsebundle, but it has not worked. Is there any way to repair the sparsebundle so I don't have to forfeit 6 months worth of backups?

Thank you in advance.

2010 MacBook Pro i5, and many many others, Mac OS X (10.6.4)

There's no reliable method. That not-so-clear message means your backups are corrupted beyond OSX's ability to repair them.

See #C13 in Time Machine - Troubleshooting.

Could you elaborate on your "few modifications"? I'm desperatley trying to fix my image and I've followed the guide by Garth Gillespie several times, yet without success so far.

I appreciate any help. Thanks!

Hi, I followed that guide exactly, except I ran the "diskutil repairVolume" command instead of the "fsck_hfs" command. For the final step, editing the plist file, you need to right-click on the sparsebundle and select "show package contents". Hope this helps.
