Backup Disk Not Available - Time Capsule After working fine for months, my wifi Time Capsule backups fail, returning a "back-up disk not available" message.  Time Capsule light is green, Airport Utility reveals no problems.  What do I do?  Thanks.
I see this every few months and all other features of the device seem to work fine when it happens. The short answer is a restart has always fixed it for me, either from the Airport Utility or if you must by cycling the power.
