You should do it this way:

- install your 80G as Master on the cable at position number 1 (closest connector to the motherboard)

- flash the player with the Mk2 Builder image, and let it run

- flash the player with the developer image, then follow the instructions in Roger's article to format the music partition and build the player directories

- connect with emplode and allow the FSCK to run and get a built database together.

You should be flying after this.
