Is the info on the dynamic data partition on Drive0 or Drive1?

It is on Drive0 only.

I normally backup the entire contents of both drives when I sync to my PC, not just the FID's directory. How will this affect my upgrade?

For the purposes of creating a new disk drive that is a copy of the old one, realize that:

- You *MUST* use the builder image to create the new drive so that the partition scheme is correct.

- You *MUST* apply the proper 2.0-final upgrade file to the new drive so that all the player files are correct.

- When the player upgrade is applied, it overwrites a lot of stuff from scratch, so you're probably backing up a bunch of stuff you don't need to back up because it's part of the upgrade file, above. So you don't need to back up every file on every drive.

- So all that you need to worry about backing up is:
- your music and playlists (FIDs).
- your config.ini (maybe... that's easy enough to rebuild).
- dynamic data (maybe... only if it's important to you).
- any third-party applications you've installed (maybe).

- After you restore the FIDs, you *MUST* rebuild the database files.

Finally, please note that the Drive Upgrade guide has full instructions on how to transfer one drive's contents to another in place without messing with your PC backup files.
