The ports are NOT hot swappable, nor does OS X permit them to be hot swappable.

Thanks for the reply--much appreciated.

So does a hotswap eSATA setup require a PCI card? I've been looking at this as well:

$25 for a eSATA bracket?!? Typical 'Mac' vendor rip-off prices. Same thing for $3 (+$5 shipping).

The Intel chipset documentation says:
5.18.1.3 Hot-Plug Operation
Dynamic Hot-Plug (for example, surprise removal) is not supported by the SATA host controller. However, using the PCS register configuration bits and power management flows, a device can be powered down by software, and the port can then be powered off, allowing removal and insertion of a new device.
Note: This Hot-Plug operation requires board hardware (implementation specific), BIOS, and operating system support.


And if I had to guess I'd say Apple probably didn't implement it.
