	Due to the tremendous response (great to have friends!),
I solved the problem with my 800k disk drive. Since there were
over 15 replies, and basically three suggestions as to 
what might be wrong, I thought I`d summarise here.

	Here was the problem:

	Apparently this is a very common problem! These 800k drives
are overly sensitive to alignment, and their eject mechanisms are
not very sturdy.
	The first suggestion involves disks with too many labels 
attached or with a label that is not attached completely. Some said
that a label or portion of a label came off in the drive and fouled
up the eject mechanism. I examined my drive and couldn`t find any labels
or portions thereof.
	The second is that the drive needs to be carefully aligned to
the Mac case, or the disk may rub against the opening, and the eject
fail:

	This is what I did. However, it turned out that the dealer who
mounted my new drive only put three screws in, instead of the four
required. The crucial missing screw was at the front right, and
the disks were indeed rubbing against the front right of the bezel.
I am currently attempting to get the dealer to give me another screw...
but more on that later...

	The final suggestion was more exotic, but also seems plausible:
----------

>Pry the back off slowly and carefully.  
2) Pull off the logic board (detach the ribbon cable connecting it
to the power supply first). Unscrew the screws which mount the 
drive and detach the ribbon cable from the logic board.

There was even a suggestion to solder a metal reinforcement
onto this arm. Luckily I don`t think I need to try this.
	Finally, many people remarked that my dealer was being
unscrupulous in claiming they were going to charge me for warrenty
work. Given that the problem was their fault in the beginning (missing
screw), I certainly agree. However, before being guilty of possible
slander, I`m going to have another discussion with them about their
policies. If they persist in the behavior, I`ll certainly post the
name! (That`s a threat :-( ).
	Thanks for the help! Its great to have such a support group.
