Some software may attempt to access optical drives using SPTI (SCSI Pass-Through Interface).I recommend and use the Adaptec solution. (V4.60 is on the Adaptec site, and other locations on the Internet) Other options are the free Nero ASPI or FrogASPI. If you find that V4.71.x doesn't work, or behaves in an erratic manner, try V4.60 it seems to have less hardware compatibility issues. CAUTION: Some users have reported problems with the latest V4.71.x family of ASPI from Adaptec. You can use the one supplied free of charge from Adaptec. Many authoring packages and tools require a suitable ASPI access layer be installed on your system to control the ATAPI or SCSI optical drives.
Software is often 'bundled' with CD/DVD Writer hardware - a lot of this software may not be suitable for NT4.0 - proceed with caution.See here for a much more detailed rundown on ATAPI and D.M.A. Ensure that drive master/slave jumpers are correctly set. access modes with a standard 40 conductor ATAPI cable. (Whilst you are at it, check the bus cabling and settings for your Hard Disk Drive(s) is also correct) An example of 'misconfiguration' would be attempting to use D.M.A. Ensure that the bus you have the optical drive(s) connected to is properly configured.High end hardware (Celeron and P4 2.0GHz + systems) should be capable of driving any optical drive to maximum throughput, subject to limitations brought about by the interconnection bus.A Pentium classic at 133MHz should be able to manage a CD write at 1 or 2 spin satisfactorily.In CD terms, this equates to stable writing at around a maximum of 18 spin. Pentium III at 700MHz, using correctly configured hardware, can write a DVD at 2 spin, but would be challenged at 4 spin.A Pentium classic at 133MHz is MOST UNLIKELY to have sufficient computing 'horsepower' to be able to successfully operate a DVD writer at all. Be realistic about the processor speed requirements for 'burning' optical media.Fortunately, nearly all modern hardware satisfies these requirements. This article is a little dated, what is said about CD recorders applies equally to DVD recorders. See Knowledgebase article 141379 - "Using SCSI CD-ROM Recorders with Windows NT" for further details. The CD or DVD Writer must be compatible with Windows NT 4.0.Below are my recommendations and observations on what needs to be done to ensure a successful system. Correctly set up, NT 4.0 (both Workstation and Server) is capable of excellent results. The reality of the situation is in fact the exact opposite. Writing (and to a lesser extent reading) optical media (CDs and DVDs) has always been an operation which several 'experts' have claimed NT 4.0 was incapable of performing.
