You are aware that a typical modern hard disk actually exposes very
little of its internal geometry to the world, surely? The range of
LBAs that you address over the IDE/SCSI cable could well be scattered
across multiple platters, multiple heads or (depending on the
particular setup) even multiple drives. Trying to second-guess the
physical layout of data is generally a mug's game...
