I have an eSATA external hard drive case. I want to hotplug / unplug it.
My system is Fedora 11.
I added an external eSATA port on my desktop computer by adding a bracket
(with an internal cable connected to one of the ordinary SATA sockets on
the motherboard.)
The SATA controller is an intel ICH9R. To make hotplug work, I needed
to go the computer's BIOS and change the SATA mode to AHCI (it was
IDE).
I can now hotplug the drive.
I cannot unplug the drive. If I tell the system to eject the drive,
it complains:
# eject /dev/sdi
eject: device "/dev/sdi" doesn't have a removable or hotpluggable flag
# cat /sys/block/sdi/removable
0
(I don't know where or what a hotpluggable flag is.)
I guess that makes sense: the system doesn't know that I added an
eSATA bracket.
What are the reasonable ways to tell the system that that SATA port is
an eSATA port and should allow for hotplugging/unplugging?
My guess is some kind of HAL rule but I'm not an initiate. Maybe
something in here would work:

Surely lots of people have already encountered this issue. If so,
there ought to be a non-wizard way to handle it.
