Your manual explains how to backup and restore your music database (pp.38-41). Formatting your new drive is covered on p.62. Looks like you'll need an external USB drive with a larger capacity than the size of your music database.
Here's how I would do it:
1. Backup music DB to external drive
2. Remove old drive
3. Install new drive
4. Format new drive
5. Restore music DB from external drive
