Hi, can anyone help me with my problem? I want to delete backup of my iMac from TimeCapsule to create a fresh new one. But it seems not so easy. I've turned off TimeMachine on iMac and tried to delete sparsebundle from TimeCapsule via Finder. Result is infinite waiting for removal in Finder dialog window. I've tried to select 'no backup disk' in TimeMachine preferences but got the same result. All software and firmware are updated to latest versions. I cannot erase the whole TimeCapsule drive as described in other posts here because I have a backup of my MacBook Pro on it and I need to keep it.
Sounds like the same issue I had...I thought 2 hours would be long enough, so I cancelled the delete and that's left the time machine not working (for one of the computers...all the others are still backing up OK).
How long did you have to wait? (My sparsebundle is 500Gb)
