Several phone calls were placed to you and none returned. Between SCO and Micropolis there was "well, it should work" but we could not get any help from Adaptec to make it work. In the meantime, when time is of essence, one has to look for other alternatives. The advice from technical support at Adaptec was to try a variety of other things, but disabling the cache (I guess that is the read-ahead) was not mentioned. After several days of format attempts it becomes cheaper to go to another vendor that guarantees his controller to work and offers more documentation than the meager handout from Adaptec. Even to this day, no one on the net has that drive with that controller working. At least no one has come forward. Some SCSI controllers, yes. Other drives, yes. Even lots of smaller 330MB drives. I suppose the old lesson about never assuming anything to work until proven otherwise has stood the test of time again. One of these days when we have more time, we'll give it another shot. fred rump -- Fred Rump | UUCP: {uunet bpa dsinc}!cdin-1!fred CompuData, Inc. | or ...{allegra killer gatech!uflorida decvax!ucf-cs} 10501 Drummond Rd. | !ki4pv!cdis-1!cdin-1!fred Philadelphia, Pa. 19154| Internet: fred@cdin-1.uu.net (215-824-3000)
