When I first started storage-fixup.  I thought it would be a temporary
thing and vendors would pretty soon stop shipping broken devices.
Well, that doesn't seem to be the case and storage-fixup is really not
the solution.  It will always cover only small fraction of actual
problem cases while unnecessarily increasing power consumption on many
configurations.  It's too small and too big a solution at the same
time.  More succintly, it sucks.  :-)

I've been trying to contact vendors and am talking with at least one
of them but if vendors are okay with the current situation I don't
think there is much we can do.  It's a problem between hardware
vendors and their customers and I don't think it's wise to continue
providing this half solution which is doing more harm by masking the
real problem.

Thanks for reporting and I'll add your entry to storage-fixup and also
update ATA wikipage in several weeks.
