Most of my time is spent in Win 2K, BUt under 4.0 Nt will recognize native IDE devices without and effort..Simply by installing them NT will see the device but the device may not fully function. I installed on cd rom and NT called it a cd rom, but would not read from it until I installed the right driver. Assuming it's installed correctly (slave, master, etc.)Once you have it installed, from control panel you will see an applet for scsi devices. You can install the driver from there, or I believe you can also just copy the appropriate driver to the winnt/system32/drivers and reboot the computer. I would try the first option.
