AFAIK there are no native 4K sector drives on the market yet. All of
the currently shipping models with physical 4K sectors are "Advanced
Format" drives. The Advanced Format standard specifies 4K physical
sectors -internal- to the drive, but with traditional 512B LBA addressing.
Dwight, what disk drive is this in question? Make/model?
