I'm afraid not, because the above error starting with "ERROR 4:" is
issued by gdal, not grass. Therefore any gdal program will report the
same error.

I noted some strange single quotes in the above r.in.gdal command.

Can you try
r.in.gdal input="/path/to/HFZ/5m_irish_sea.HF2" output=test title=test
instead of
r.in.gdal 'input=/path/to/HFZ/5m_irish_sea.HF2' output=test title=test
?
Although I don't think this really helps...
