Don't use a partition-table format that dates back to drives with actual reported physical geometry and which also maxed out at 2MB or so? Even the mac-format partition tables (which aren't that much newer) don't care about physical drive geometry. Besides, unless you're running DOS, Windows 95, or some random ancient firmware that looks at your partition tables or whatever you can just tell fdisk to ignore the 63-sector-alignment constraint and align your partitions more efficiently anyways. But if you're dealing with hardware so new it supports 4k or 8k sectors, you really should be using EFI or something.
