No. I'm sure that isn't true. See the idectl command.
Also see 'hdparm -U' and 'hdparm -R' which allow to un/register devices
on specific IDE channels. I suspect idectl is doing much the same thing.
Ahh. idectl is supplied as source in
/usr/share/doc/hdparm/examples/idectl...
Should be what you want :O)
