Can't delete

That means something is trying to use the sparse bundle. Make sure it's dismounted.

Or, if there's nothing else on your Time Capsule, just erase it. Use +*Airport Utility.+* Select +*Base Station > Manual Set-Up+* from the Menubar, then Disks in the tool Bar, then Erase.

How do I dismount it?

Erasing is not an option. There are 2 MacBook backups on it, my wife's and my daughter's. Neither are here and redoing their backups would be difficult, perhaps impossible.

Sorry, I probably should have said Eject it. If it's on your desktop, right-click it and choose Eject. If it's in a Finder window's sidebar, it should have an Eject symbol next to it.

If it's not shown either place, try +Finder > Preferences,+ then either General (for your Desktop) or Sidebar and check the +External Disks+ box.

If it's still not shown, start the +Disk Utility+ app in your Applications/Utilities folder. If it appears in the sidebar, select it and click the Eject symbol in the toolbar (or +File > Eject Disk Image+ from the menubar).

If still no help, try +Airport Utility.+ Select +*Base Station > Manual Set-Up+* from the Menubar, then Disks in the tool Bar, then +*Disconnect All Users+*
