Thank you very much Tejun. I promise I'll be looking for such a tool next time before I bother any of the kernel related mailinglists. My Hitachi is now officially running at 3.0Gbps .. and I even managed to enable some of the other features (Accustic Management and Power Management).

Nevermind here, I'm a long term C lover .. so it wasn't all that complicated to adjust the patch. Besides, you've been very kind in providing a patch at least .. since otherwise I'd have to dig one up myself (and I am lazy as well ;-). Thanks again. Regards, Moritz
