Overheard at Fry's, a guy advising his friend to be careful in partitioning high density drives to be aligned to multiples of cylinder ( or something ) boundaries otherwise the HDD firmware/hardware would be busy constantly adjusting offsets during reads and writes?

I also heard him use the term "4K cluster sizes".

I assume almost all the >500GB drives fall under the high density category?

Is this partitioning caveat true?

What is the story/reason behind this ( even if this is no longer applicable for newer hardrives ) ?

They were talking about Advanced Format hard drives. Not all hard drives have this feature.

Great answer! This is only for such WDC Drives or do other vendors make them as well? –  PoorLuzer Oct 24 '10 at 0:49
Eventually all makes will move to this technology, not sure who has and has not so far, see this article....bit-tech.net/news/hardware/2010/02/02/… –  Moab Oct 24 '10 at 2:04
