What Hydra are you using?
What is your machine?

The only one listed on the site is
Hydra Systems AmigaNET Zorro     A4000     NO     

This means it's the only one tested.
Doesn't really help you much, I know.

I would say in that case, it doesn't work.

In the case of the FastATA for instance, there were no OS4 drivers supplied, but the existing ones worked under emulation.
And that is listed as working so the Hydra would also if that worked with drivers under emulation.
