That holds true for thinkpads up to the T43, at least. I don't know about
the newer ones.

You *do* have to worry about it in any box you turn off daily.

Check if /etc/init.d/halt is calling halt(8) with the -h flag. If it is,
remove that -h flag. Usually, there is a hddown variable that holds it, you
just need to get rid of it.
I don't know anything about a Sidux, though.

Actually, editing /etc/init.d/halt is enough. Find the hddown="-h" and
change it to hddown="".

If it happens just under Linux, this is something that really needs to be
addressed post-haste. Maybe someone should open a bug in bugzilla to help

either fix or give you your money back).

Ah, now I understand what you mean.
Looks like we really need the dock driver to sort of like act as a bus.
