Any >advice and/or "war stories" will be appreciated. Bunk. Enable translation mode and off you go. We use the WD1007-WA2 boards with Maxstor XT4380E drives all the time (16ms, 338MB), they work fine. You end up with something that the system thinks has 63 sectors per track, and some strange number of cylinders and heads, but it works. Plug it in and go if your drive is preformatted (most ESDI drives are). -- Karl Denninger (karl@ddsw1.MCS.COM, <well-connected>!ddsw1!karl) Public Access Data Line: [+1 312 566-8911], Voice: [+1 312 566-8910] Macro Computer Solutions, Inc.

That's good to hear; I'll have to check into it as soon as the GT release is
available for public consumption :-)
