I have a mid-2010 Macbook Pro. It came with a 500G internal. For a couple of years, I've been using a 1TB external for Time Machine backups. As of a couple of weeks ago, I'd reached only about half of the capacity of that external HDD.
Last week I swapped my 500G internal for a new 1TB internal. Before I did that, I cloned my internal with SuperDuper. Then I switched HDDs and migrated everything over. No issues. So now I have a new 1TB internal with about 600G free.
Tonight I hooked up my regular Time Machine to the MBP. It didn't automatically start backing up, like it used to. I figured it was "used" to the old internal, so I manually selected my new internal and it started to backup..... the entire drive. Not an incremental backup (probably about 30 gigs). I checked the contents of the Time Machine external, and all the old TM backups are there, perfect and accessible. Why won't it scan my new internal and back up only the changed or new files?
