You're right.  The HardFrame is fast enough that you should leave it at 0.

Yes.  If you make sure the partition start and end at the exact same place.
If all you change is the MaxTransfer or some parameter that doesn't relocate
the partition or change it's size, you shouldn't need to reformat.  When
I "retuned" my HardFrame after a month's use (changed the buffers and
MaxTransfer) I deleted the partition info, reentered it with the changes, and
rebooted--the changes took effect and no data was lost.  Of course, I *did*
backup my drive before, just in case.  As a matter of fact, I discovered that
I had goofed on the first partition's ending cylinder but everything was fine
after I fixed it and rebooted.
