It can depend on your motherboard chipset. While eSATA should be a hot plug service, some manufacturers are a bit slack and use a standard SATA controller without hot plug capability and then just put an eSATA connector on it.

To test this, shut down your system, plug in the eSATA device, and power up the machine. The system should recognise it in the BIOS and then Windoze will find it. If the BIOS doesn't find it there is some other kind of problem happening.
