Many of the actual ATA standard revisions actually state this also for
parallel ATA.  Point-to-point UDMA is not supposed to be between more
than one drive.

Of course, the legacy Programmed I/O (PIO) Enhanced IDE interfaces
allowed this, hence why vendors kept offering it even for UDMA drives.

It is mathematically impossible for someone who makes more than you
to be anything but richer than you.  Any tax rate that penalizes them
will also penalize you similarly (to those below you, and then below
them).  Linear algebra, let alone differential calculus or even ele-
mentary concepts of limits, is mutually exclusive with US journalism.
So forget even attempting to explain how tax cuts work.  ;->
