I dove into a friend's Mac+ the other day -- she was having the exact same
trouble.  The solution involves opening the case, removing the disk drive
enclosure and the disk drive from the enclosure.

Right.  Whatever you do, DON'T pull on the disk.  Follow these steps:

1) Open the case.  Torx-15 screwdriver required, must have a long arm or it
won't get the screws in the handle.  Remember, there are five of the suckers
(one in the battery compartment).  Pry the back off slowly and carefully.

2) Put Mac on it's face and examine the bottom of the logic board.  If you
can't see the screws which secure the disk harness to the case, you'll have
to remove the board (I don't remember whether or not I had to pull the
board).  I think though, that you don't have to go so far.  Unscrew the
screws and detach the ribbon cable from the logic board.

3) Once the harness is free, go to work on the screws which hold the drive
in the harness.  Once the thing is free, look at it's "left" (as seen from
the front) side.  You may want to take a spare disk and examine it (look for
the small circular notch on the disk's left underside near the metal door).
The disk in your drive is being held by a small arm which swings into the
little indentation on the side of the disk, and which SHOULD swing out and
allow the disk to move freely after you use the ol' paperclip routine.  If
you try that now, you'll see that the arm doens't move far enough out.  Take
a needle-noser and VERY GENTLY bend the arm outward.  Voila, the disk is
free.  Work it in and out until satisfied.

>$60/hour!!!!) 

Make that $100/hour in some places.  You can now undersell the b*st*rds
nicely.

GOOD LUCK!
