Best to give up, but you could pull it apart and replace the hard drive for under $100. I did and still found my unit was broken. The time capsule is a piece of junk. The airport without the hard drive is a more functional unit. I bought one and a hard drive that with a usb enclosure to connect a hard drive. I don’t trust the time capsule with my data. Seems to have heat sink issues that burn up the hard drive and internals.
