I bought a Quantum Atlas scsi disk drive (XP34300) and connected it to my Adaptec 1742A scsi adaptor. I have a micropolis disk as scsi id 0 and the atlas is scsi id 1. The adaptec is scsi id 7. I started from DOS and ran fdisk fine. Then I tried format. All went well until the end when it was going to write the label. At this point, the system froze with the drive and adaptor busy lights on solid. I tried doing a few things with the drive and almost everything resulted in a freeze. I contacted Quantum and they said there was a timing problem between the atlas and the adaptec 1742 and gave me a firmware upgrade for the disk. It completed with no error but the freeze still happens. Trying to access the disk from FreeBSD results in a freeze as well. Any ideas? Tom Proett
