IIRC, 33 sectors was the classical cylinder size, and cylinder
alignment was required of partitions. While this is no longer
the case, many programsa (bootloaders, boot sector backups, etc)
expect the zero'th cylinder to be empty (sans the MBR sector)
and available for their work. So other tools play along ;)

Well, that is possible - some usb-flash raid sets were in YouTube Sun 
marketing clips ;)
