[ETC...] Based on the information posted, this conclusion seems premature to me. You made both a hardware AND a software changed and after finding problems, you make the assumption that Atari's software is 99.44% likely to be at fault. This doesn't seem very fair to Mr. Pratt & Co. I suggest that you remove the 40 meg drive and put the 10 meg in its place and test the set-up as best as you can. If this set-up works fine, your problem might not be software related at all. You might also want to try setting the 40 meg as unit 0 and the 20 meg as unit 1 and see if the problem stays on unit 1 or with the 40 meg. Finally, you could try going back to your old software and see if your new hardware works properly. Don't get me wrong, you may have identified the problem accurately. I'm just suggesting that you try some tests to confirm your theory. Maybe your intent was not to blame Atari, but that's how it sounded to me. Good Luck, Ron Abramson P.S. These opinions are my own!
