You need to have the drivers installed for your sata controller. The stock windows drivers won't work. If you have a ICH8/9/10 southbridge, you'll need the Intel Storage Matrix driver and software to allow you to hotswap sata. If you have an nvidia chipset mainboard, you'll need the Nvidia chipset drivers. Either way you need to make sure you have the latest storage drivers for your system's motherboard to support hot swapping.
