Operating System: Windows 2000 Pro (Note: might work with other versions of this os.)
There is a firmware upgrade available. This update corrects a time problem that affects the drive's ability to read blank media. HP recommends this update for all 9100 series drives. They suggest the firmware should be updated before upgrading to Windows 2000. I just ran the upgrade under Windows 2000 and had no problems. Seems to have fixed the problem.
