HD drives can be used with TOS 3.01, too. The only problem is that you
cannot select the "HIGH DENSITY" option because of a bug in TOS. So you
have to format your HD discs in another way.

I have worked with the TT and HD drives for a few months now. There are no
major problems but my controller does not like the 16 MHz used for reading/
writing HD discs. When the controller warms up I cannot use HD discs any more.
So it depends on the controller if you are able to use HD drives without
waiting for a new controller chip.
