I use a 480GB SSD under the armrest of my F31 for USB audio. I recently deleted some MP3 files on it and replaced them by FLAC files of the same albums in the same directory structure. The car refused to play the new files as it didn't re-index the drive and see the change from .mp3 to .flac file extensions - it just thought the mp3 file had disappeared. It looks like the car relies on its cache of the index rather than what's really in the directory.

Renaming the SSD with a new name forced a (lengthy) complete re-index process and I could then play the files. I'm wondering, however, if anybody knows a way to force a re-index from within iDrive so I don't have to keep renaming the SSD every time I change files on it?

(Before anybody says that iDrive doesn't play FLAC, it does since a recent software update so that's not the issue).

GREAT question...I also wondering how would the car recognize new files added as well? I plan to add a 1tb drive and update it every few weeks as I add new music.

I think it depends on the size of the external HDD. personally, i use a 64 gig usb stick and when i add some new files on it, it takes up between 5 and 30 minutes before the system recognizes the new added files. I don't think you can force this action.
