Is SATA always hot-plug?

I just got an external drive case (Rosewill, FYI) which includes an
internal to eSATA bracket. Now on one of my systems, there is no SATA
support on the motherboard, so I got an Adaptec SATA controller, which
works great.

If I connect the cable from this internal to eSATA bracket to a spare
port on the Adaptec controller, will the external port automatically
be hot-plug?

I'm not sure I'm explaining this too well, but I hope everyone
understands what I am asking about.

Thanks.

- SATA is electrically always hotplug, if you use the SATA
power connector.

- For the data connection, it depends on the controller and
the driver/OS. The HDD always supports hotplug.
One Hint: AHCI supports hotplug, while IDE emulation does
not. You hay have to change some settings in the controller
BIOS.

Unless the bios doesn't have AHCI, like on my P31 motherboard.

Some other controllers support hotplug under Linux. No idea
about Windows.

If you go to device manager or disk management and refresh many IDE-mode
controllers will notice new SATA drives.

Thanks to all who replied. I will try this out as soon as I get a
chance.
