My hard drive crashed and burned. Apple replaced it and I had full recovery thanks to Time Machine. But now that I'm up and running I get the following error message when Time Machine attempts to backup: "Unable to complete backup. An error occurred while linking files on the backup volume." I can't seem to find out what this means. I"m guessing that it has sees some disconnect between the previous backup set and the new one. Do I trash all the previous backup sets and run a new one as if starting from scratch? Thoughts, advice?
