Recommended hot-plug eSATA PCI cards?

[Scott Ehrlich]

lspci shows the card just fine.   The eSATA hard drive works just
fine.   If the eSATA drive is plugged into the PC while the PC is
already powered on, the drive is not seen.  I'm not looking to boot
from the eSATA drive.  Simply interact with it.

But, if the PC is restarted, but the eSATA drive remains powered on
and plugged into the PC, then Linux sees the drive.

I happen to be using a startech PCI card whose documentation says
nothing about having a hot-pluggable eSATA port and happens to use VIA
chipset.   I say these as a point of information (aka fyi).

Documentation on at least one Promise eSATA card does say the eSATA
port is hot-pluggable.
