A quick search on Google turned up ATA command "Set Features" and SCSI
command "Read Long", though both had caveats (not all drives support them,
that the command may only work on drives up to some maximum size).  I'm not
a coder, nor do I pretend to understand how the guts really work.  For all
I know, it could just be advertising hand-waving that occasionally actually
works.
