One final note ...

"libata" is an effort to give a rich set of features to both
ATA and SATA.  Especially for SATA, where it does have
staggered pins and can be considered the "SCA for ATA."

But that means the ATA controller, its driver and the
end-device must all support the function in libata to work.
