As you've already found out, no. However, I can tell you one controller that definitly will work with a Maxtor 380Mb ESDI drive. I just put one on my Webster WQESD controller, and although I've not put a OS on it yet (I'd accidentally put a manual I needed in storage), I did extensivelly test it out with the controllers build in diagnostics.
