You understand that it's only semi-hot, right? Or at least that it's not
automatically hot-swappable . . .
You have to do an
atacontrol reinit
after insert or removing, and of course you have to mount & umount as usual,
and in the sensible order; eg, to dock:
(physically dock)
atacontrol reinit 1
mount /whatever/is/on/the/second/channel
To undock:
umount /whatever/I/mounted/before
(physically undock)
atacontrol reinit 1

I've been running it for a while now and it continues to be stable for me,
BTW.
