And that is really the important point from that thread. |

I believe you're correct. |

Yes. Cylinders do exist on the disk but they are not something to be |
26 |
used anymore. |

No, not as I understand it. |

There may be some bits of software that suggest they can use them, but |
34 |
I think with the advent of LBA directly addressing CHS is now retired |
35 |
with only sector addressing being important due to the way the data is |
36 |
physically placed on the drive. Who cares what cylinder it's on, and |
37 |
who cares which head is getting the data? It doesn't matter to us |
38 |
users... |
