Press the eject button. Seriously.

The thing is, you will not 'hurt your Amiga' by ejecting a disk, whether the
light is on or not, despite warnings to the contrary. Do not take this to mean
that ejecting the disk while the light is on is A Good Thing, because it
usually isn't. However, what we appear to be talking about here is an unusual
situation. Some program has messed up or was written in a way that doesn't turn
the light off, or perhaps you have a hardware problem.

If the light is on, it means that some code has turned it on.  This will happen
if the disk is being read or written.  If it is being read, the worst that will
happen is that a read error will occur, and you will be asked (sometimes
strongly) to replace it.

If it was being written, the worst that will happen is that you will get a
write error, and the disk will be unreadable later. If you are lucky, you will
be asked to replace the disk, and the write operation will finish. If you are
not so lucky, the diskette will have read problems, but that will be true with
a reset too.

Note that the reset (three fingered or power off/on) will do essentially the
same thing to a disk that is being written to. Program activity stops, and
nothing further has a chance to be written to the disk. At least with the eject
button, you have a chance of having everything turn out OK.

The warnings against ejecting the disk while the light is on are definitely to
be heeded during 'normal' operation.

Sometimes I have problems with programs (games and demos) that uses the disk
(at least the green light is on) all the time, so I don't know how to get the 
disk out without hurting my amiga.
I have tried first resetting the amiga and then ejecting the disk but 
sometimes I end up with a diskdrive that simply can't read anything without
several C-A-As.
Do anyone know a better way to get the disk out?

Beg to differ all you want, but I tell you there is no difference between
ejecting the drive with the light on or with it off, in any physical way. The
heads are not of the 'load when in use', 'unload when idle' variety. They are
always 'loaded' and in contact with the disk. If you press the eject, the same
things happen whether the light is on or not (execpt that if you are writiing,
you will end up with a clobbered track.

I once did exactly the same thing as you did, but while the light was off and
the drive was not spinning (I fixed it myself).

Oh, I beg to differ!  I once ejected a disk with the light on and caused serious
damage to the floppy. I managed to unclip the clip that holds the head assembly
to the drive.  Only with the help of an electronics surgeon was I able to
get the thing reclipped without a $100 charge from a repair center.
I think it is much better to reset and then pop the disk than it is to
pop the disk with the light on.          -- Darren
