Is the info on the dynamic data partition on Drive0 or Drive1? I'm only going to be replacing the secondary drive in my players, so if the DD is on Drive0, that will make it much easier. BTW, 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? Should I just replace the FID's when I'm done replacing the second drive? That's how the Drive Upgrade Instructions read to me, but since I have a complete copy of Drive1 I was going to just dump it all back on the player.
