time capsule does not appear in shared devices

That is bad.. the light should not be green unless you told the TC to ignore the problem.

A damaged disk has to be replaced.. if the SMART has gone off or is showing as bad or no capacity then you need to replace the disk (or if under warranty.. the whole TC).

How old is the TC?

Model number from the base A1xxx helps.

You can try doing an erase from the airport utility if the disk shows up at all. But if SMART has gone off the disk will need replacement anyway.

If less than 1year return to apple for warranty replacement.. and if you have applecare on a computer it will cover the TC for up to 3years although the rules are strict.. so check.

See instructions for removal of the hard disk.

Certainly if the TC is older than 3years.. it might be better to consider replacement. Certainly replacing a hard disk could be just short fix until the power supply also goes.

I did tell the TC to ignore the problem because I was hoping that would let me mount the drive.

It is a next to last generation TC bougth in March 2012... I guess it is out of warranty 😟... I am work today, I will contact apple tomorrow when I get to work from home.

Thanks for your input

Same thing happened to me with the TC and HD itself going bad. If you don't want to risk data loss, ditch the existing TC, extract and rehouse the HD and connect it to a new TC (or your preferred less intuitive network) and reconfigure to have the old TC disk recorgnised on the new TC via Ethernet.

It cost me about $50 and a few hours of time but gave me full access and time to move the data then reformat the old TC as an external HD after low level repair.

I can do it for you but you'll need to send me the old TC and a small fee.
