I have a 320GB Western Digital IDE drive. When I built my new system, I used a Vantec IDE-to-SATA conversion kit and it is now plugged into a SATA channel on my mobo. My 2 optical drives use the IDE channel. But ... in Win-doze, the drive is reported as USB!! Thus when I use my thumb drive I need to exercise caution on drive disconnection. The "How come?" question: How come an IDE device plugged into a SATA channel reports as USB in the OS? No, I have no RAID setup ... this is the only HD in the box.
