Note, in the graphic above there are no RAID controllers on the system. Check in this area to see if there is any devices (drivers) installed for a RAID controller.
If there are no RAID controllers installed, then you don't have a hardware RAID implementation. Next, check if the system is running a software RAID product, such as Veritas Volume Manager, by checking in installed products for Veritas Volume Manager. This software package is a software-based RAID product and is also part of Veritas' Storage Foundation Suite for Windows. There are some other implementations of RAID systems on Microsoft Windows 2000, but these are the basics that will help you ferret out what is installed.
