Sorry, I guess I was confused on this point then.  It's been a long time
since I played with an RX02 :-)

But, I think the accurate notion is:

  63 arises from ancient history, and is now tradition,
  it doesn't make sense with modern disks,
  especially with 4K physical sectors

And I suspect most people agree on:

  one should use a multiple of 2^k 512-byte sectors for some decent k
  for aligning.

  popular values are 64 and 2048.
