I don't agree with:-

"Linux pays attention to the hard drive's actual geometry, and would not
split this file so badly."

I was under the impression that Linux has no clue about the real physical
geometry of the disk because that's abstracted by the circuitry on the
drive/controller. As far as Linux is concerned it's a large number of
sectors, it has no clue *really* how they're arranged.

That's my understanding anyway.

Cheers,
Al.
