Update on issue - - -. Booted from a 4-week old SuperDuper backup (on a Firewire drive). Held Option key while powering on. Operations are very slow and I don’t know if I’m responding to the SuperDuper or iMac messages. Got boot disk options - Macintosh HD; recovery disk and SuperDuper disk. Selected SuperDuper and logged in. Got information message: “OSX can’t repair the disk Macintosh HD … you can still open or copy files … backup and repair a.s.a.p."
Started Disk Utility and Verified disk Macintosh HD. After step “check catalog file” got messages in red: Invalid key length. The volume Macintosh HD could not be verified completely. Error: this disk needs to be repaired. Click Repair Disk. Did Repair Disk and got message “Error: Disk Utility can’t repair the disk - - - reformat - - - and restore files from backup.” Sounds rather serious. I did not reformat disk. Any advice (apart from having a strong coffee - - -)?
