Now try to perform a Time Machine backup from
one of your Macs to the Time Capsule drive. If it
succeeds, then data may have corrupted on the
drive for some reason, but it’s still functioning.
If you get a failure in Step 3, 4, or 5, or can’t back
up to the Time Capsule after Step 5, you should
remove the Time Capsule drive as a destination on
every Mac that’s been backing up to it, otherwise
you’ll receive regular errors on each Mac. Open the
Time Machine preference pane on each Mac and
remove the drive from the list of destinations.
If the Time Capsule drive won’t accept backups,
it’s failed in some sense of the word. Most people
will find the steps to replace the internal drive
are too involved and not worth the effort. You can
instead attach an external drive via USB to the Time
Capsule and use that for Time Machine backups, or
attach a drive to any Mac on a network and use it a
networked destination instead.
