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What is the story/reason behind this ( even if this is no longer applicable for newer hardrives ) ?
