Time Capsule shows with wrong name on Time Machine

Thanks Bob, this website is very interesting! After trying many of the suggestions there without success (including a hard reset of the Time Capsule and changing all names yet again to avoid the apostrophes), none solved the problem. However, # C12 gave me an idea that I think will work.

I think the solution is to go to Airport Utility, select the Time Capsule, and then click Manual Setup. There, go to Disks and manually change the name of the Time Capsule Disk to the new one. This managed to solve the problem to backup my iMac. I seemed to still have trouble backing up the MacBook Pro, but I am going to backup the iMac tonight, and see if I can tackle the MacBook problem tomorrow. Both computers have the same system running (Leopard Snow), but I did mess up a lot with the MacBook trying to solve this today, and I may have created a new problem. I'll report tomorrow about how things are going with the MacBook. The iMac is thankfully backing up now.

Thanks again, I am definitely bookmarking that website!

Ok, the MacBook is backing up now. Here is what I did:

After manually changing the name of the Time Capsule Disk as above, Time Machine was still not able to back up. I kept getting the error message

"Time Machine could not complete the backup. The backup disk image "/Volumes/Old Time Capsule name/My laptop name.sparsebundle" could not be accessed (error -1)."

The problem is that "My laptop name" Time Machine was using is wrong. I had changed the laptop name in Network Perferences>Sharing before, but it still kept looking for the wrong .sparsebundle file in the Time Capsule. I don't know why, and I even deleted the NetworkInterfaces.plist file again with no success.

I entered the Time Capsule from the Finder menu, found the .sparsebundle file with the wrong name, and manually deleted it. Finally the MacBook was able to backup. However, although the MacBook name is the same as it used to be before, and even though there was already an old .sparsebundle file with the correct name, Time Machine created a new .sparesebundle with the same name, and began an entirely new backup. I am just letting it do this backup, and then I will manually delete the old backup, so it doesn't take space on the Time Capsule. I don't need the past backups (and hope I won't swallow my words), and I am tired of dealing with this, so this will be it.
