One of my clients has a Windows XP box with 9 Pioneer DVR-109's all attached to 2 SCSI cards. One has 3 drives, the other has 6 split between 2 connectors. The SCSI cable is then connected to a SCSI to IDE converter at each drive.
This setup worked flawlessly with just CD-RW drives. When trying to burn DVD's, they fail like crazy. The machine is a 3.0GHz P4 with 2GB of RAM. its only job is to pull images off a server using a gigabit connection, and burn them to several disks at one time as fast as possible. Currently, the fastest possible is 3 drives at 1x. I know the PCI and SCSI buses are nowhere near being flooded, the Network utilization is under 10%, and the CPU utilization is under 25% during the burn process.
What can be going wrong here? I have tried alcohol 120%, RecordNow 4.6 (supports multiburners, and clients preferred app), and i will soon be trying nero.
Does anyone have any suggestions? Its costly to let it fail on some many drives at one time, so I need a solution ASAP. Thanks!
