We ended up getting a new drive from HP and it worked just fine. But I think what realy fixed the problem was upgrading the rom ont the drive. The ROM version is displayed in the probe message. I think the original version we had was 1.25 and the new drive had 1.26. The HP web page has the new rom version & the program to download it. Chris Olsen colsen@compus.com
