Writing to the resource fork

Perhaps the problem is Snow Leopard -
We should assume the old resource fork is officially unsupported and not
working in SN. They've been planning on removing resource forks from files
for a decade.
Back in the hypercard days, one could use the resource fork like today's
custom properties in Rev. I would store text, sounds, binaries, images as
resources.
I remember the resource system wasn't as robust as Rev as far as file
integrity; there would be occasional problems with resources, but it worked
pretty well.

Have you tried this on another machine, perhaps one running Tiger or below?
