I can try that, wish I had a logic analyser that let
me monitor what a real
disk does...
You don't need a very high sample rate to hadle the ST412 interface
signasl, so jsu aobut any logic analysr would do. They are not that hard
to find now, but if you buy a second-hand one, make sure it comes with
the pods. Finding pods is not at all easy. Making them is perhaps a
little easier, but still a lot of work.
I am told you can now get a USB-interfaecd thing that turns a PC into a
logic analyser. Since I want ot keep PCs ase far from my electroncis
bench as possible, I've not looked into these, but I have heard good
reports of at least some of them.
