yes I have tried that I just switched the jumper

now I just put everything on the 20 gig that I added and have taken out the 12 that came with the player (it really does take longer to boot with one drive I'll have to install hijack). I did notice when I took out the 12 that there was an impression in the tape under the drive from the spindle I don't remember if I have ever taken it out before or not.
