Ever since we upgraded my spouse's iMac, Time Machine has been acting up.  My Mac store/guru guy migrated all the files from her really old G5 to her "new" (refurbished) aluminum iMac... NOT from the external HD she used for her Time Machine back-ups.  When we connected the external HD to her new iMac, Time Machine automatically made a new back-up folder and did a complete back-up to that new folder.  That was unexpected but understandable.  After that, however, subsequent back-ups take forever, and Time Machine insists on preparing tens of thousands of files for back-up every time it runs, even though the great majority of said files had not been touched and did not need to be backed up.  I will periodically check Time Machine preferences during these interminable back-ups, and sometimes it will be stuck in the "preparing" phase, and sometimes in the "finishing up" phase.  The poor external HD just cranks and cranks and cranks.


I've read many of the Time Machine-related questions and responses, but none seem to address this particular problem.  I tried putting the external HD on the Spotlight Preferences/Privacy/Indexing exclusion list, quitting System Preferences, then opening it up again and reversing the process to see whether Spotlight would re-index the external HD (per one communities suggestion I read), but that didn't seem to take place.


I have yet to visit the site referenced several times as the Time Machine FAQ gold mine; will do that next.


Any other ideas, anyone?
