Hi, I've installed an Adaptec 19160 SCSI card with an internal HP Surestore DAT 24 tape drive to a freshly installed Windows NT Small Business Server. The SCSI connection is terminated correctly and the drive is detected by the SCSI bios but not by NT. When NT starts it generates multiple instances of the event ID 9 in the System log for adpu160m. I have tried a number of different drivers from both the Adaptec and HP website and nothing seems to work. I swapped SCSI cables and even tried another identical Tape drive with no success. What's more I installed Windows 2003 Server temporarily on the exact same hardware and the tape drive was automatically detected and worked correctly. What do I try next?

try loading the scsi nt driver and the tape driver driver. Nt doesn't really auto detect. You have to tell it what it has by loading the drivers.

Thanks, I'd already loaded the drivers for both first from the manufacture CDs and then from the manufacturer websites (because the drivers on the CDs didn't work). The driver for the SCSI card is "started" according to the "SCSI Adapters" Control panel item. The driver for the tape drive however is listed as "Not Started" under the "Tape Devices" Control panel item.

That was a 29160 scsi controller wasn't it? But its working now right? So it is just the tape drive? Uninstall the tape drivers. Load only the generic provided by the system 4mmdat tape driver. I know it works with that tape drive.

No, it is the 19160 scsi controller. I have tried the generic tape 4mmdat tape dirver already and it gives the same error and does not detect the drive. My gut feel is that the problem lies with the SCSI driver, but I can't find any driver or configuration that will work.
