I am one of those guys using Sun disklabels with sizes > 1TB. And I would highly appreciate if nobody out there would make my disk drive useless by simply discarding anything larger than 1 TB. This would render our department server useless, what is everything but desirable :-)
Fdisk says:
Kommando (m für Hilfe): Disk /dev/sda (Sun disk label): 1024 heads, 63 sectors, 36187 cylinders Units = Zylinder of 64512 * 512 bytes

but do not leave sda3 useless by changing the code. If there would be a chance to make fdisk and /proc/partitions not to display negative numbers (since, though obvious, they are nonsense) it would be preferrable.
Many thanks for your help, take care
