I got the following message after Time Capsule failed to backup:

The backup disk image could not be created (Error 22)

This message didn't appear until today, though the error message also informed me that my last successful backup was a week ago.

Now, I've unselected the Time Capsule and I can't reconnect to it. The error is the same as above.

Any advice would be most welcome.

    Thanks, I updated the computer and time capsule names. Then, while restarting the time capsule, I got the following error message, indicating that the TC is still broken:

    Problem 1 of 1: Disk needs repair
    There is a problem with the disk connected to your airport wireless device. Connect the disk to your computer to repair the disk.

    Any suggestions at this stage?

    Repair your backups, per #A5 in [Time Machine - Troubleshooting|http://web.me.com/pondini/Time_Machine/Troubleshooting.html] (or use the link in *User Tips* at the top of the +Time Machine+ forum).

    Thanks, but I don't see the TC in the sidebar menu in utilities (although it is there when I open Time Machine in System Prefs). Is it possible to manual connect the TC to my laptop with a USB 2.0 A/A cable? No cable came with the TC, so I'm at a loss here..

    Read #A5 a bit closer; you have to double-click the TC in a Finder sidebar, locate the +sparse bundle,+ and drag it into the Disk Utility sidebar.

    No, the USB port is for "outboard" use only -- a printer or USB drive.

    Thanks again. Unfortunately, it's not showing up in the finder window (I have checked this option in the finder prefs).

    If I click the Time Machine icon in the dock, it attempts to connect, then I get a message that the disk cannot be found.

    If I open Time Machine preferences and try to select the disk there is nothing there.

    However, if I open Airport utility, I do see the TC alongside the message: "Airport Utility found a Time Capsule that is reporting problems".

    Any ideas on how I can get the TC to show up in the finder?

    Find out what problems it's reporting and fix them. Until Airport can connect to the TC, you can't do anything with it.

    In Airport Utility, click +Manual Setup+ and click the Status to see what's wrong. There's a lot of good info in it's Help, too.

    Once you fix that, the backup problem may well go away.

    Under Status in AirPort Utility, there is a link to the disk in need of repair. It has no name, only the disk capacity. I tried clicking update in this panel, but that didn't repair the problem.

    After renaming a Time Capsule, does one usually need to rename AirPort disks as well? How can I do this?

    Sounds like it's badly corrupted.

    And sorry, but in my previous post, I'd forgotten this is an AirDisk, not the TC's internal HD.

    Disconnect it from the Time Capsule, connect it to your Mac and try to Repair it, per #A5 in [Time Machine - Troubleshooting|http://web.me.com/pondini/Time_Machine/Troubleshooting.html] (or use the link in *User Tips* at the top of this forum).

    This is odd, because I didn't attach an AirDisk. There is nothing connected to the TC's USB port. In AirPort Utility, when I click on the TC > Status > Disks, I see "This pane shows your AirDisks" and the unnamed disk's capacity. Should there even be anything here if I'm only using the TC's internal HD for backup?

    Hmm. In an earlier post, you got this message:
    Problem 1 of 1: Disk needs repair
    There is a problem with the disk connected to your airport wireless device. Connect the disk to your computer to repair the disk.


    Either that's a generic message, or your TC is really confused!

    Yes, the TC's internal HD. Is the capacity correct?

    How old is your TC? It begins to sound like it's failing.

    Does it connect to the internet ok?

    You might want to try resetting it: http://support.apple.com/kb/ht3728

    If all else fails, you might want to make an appointment at the Genius Bar of your nearest Apple Store or Authorized repair station, or call AppleCare and see if they can help diagnose it.
