Its a real PITA to answer that. HPA is uses for
1. Hiding Windoze recovery partitions (depends on the user what is
"right")
2. Clipping disks to work around old BIOSen (want to remove)
3. Hiding suspend partitions (generally want to keep it on)
4. Clipping odd sector count disks to even sizes (want to keep on)
and more..
Ew.
As an aside, it would be nice if we could enable/disable hpa on a
per-drive (or at least per-controller) basis.
Can't HPA be used by default for new installations, and be disabled
when the user asks to upgrade a pre-hpa fedora system ?
This late in the game, looks like we're going to stick with what we've
got right now, which is HPA respected by default, and the ability to
override it at install time if the installer is booted with
libata.ignore_hpa=1. First go 'round, those with partitions in the hpa
are going to get an ugly error message, but we'll stick something in
F7KnownIssues (or whatever it is) like we did for FC6 documenting the
work-around.
