I have a two external USB drives only 1 is connected to centos 5.1 at a time.
the USB drive is SLOW compared to SATA.
The external drive suppots both connections USB and SATA.

I bought  a little $5 external SATA connector that goes into the
PCI slot area (does not actually take a PCI slot just the backpanel)
and just plugs back into one of the available SATA
ports on the motherboard.

When I turn off the external drive and put the other drive on
the connection and then power on will SATA handle that automatically?
Is there a command I need to run to tell it check for new disks?

Is this possible?
Will I have to reboot to get the swapped external disk detected.

This depends on the controller - some don't provide hotplug support. There is some info here http://linuxmafia.com/faq/Hardware/sata.html.
