I tried a 73GB Atlas II 10K drive in my VAXstation 4000-90
a few days ago. It all worked quite nicely and it was nice
to see OpenVMS V7.1 cope with something that must have seemed
unimaginably large at the time the code was written.

But the noise was just too much - a bit like a jet engine
three feet away from me. If yours was as bad and you've now
stopped noticing then YOU'VE GONE DEAF :-)
