SATA Hard drive shows up as removable device with NVIDIA nForce driver within Windows XP.
SATA devices are defined as removable devices. All SATA devices will show up in the "safely remove hardware" wizard because NVIDIA supports the SATA Hot Swap function. This is not a problem or bug but by design and is expected behavior. Please note that Windows will NOT allow you to remove a boot drive / system volume within this Windows utility.
