 Due to the use of 32-bit integers to store the number of sectors, 
 bsdlabel(8) is limited to 2^32-1 sectors per disk or 2TB in most cases. 
 The fdisk(8) format allows a starting sector of no more than 2^32-1 and 
 a length of no more than 2^32-1, limiting partitions to 2TB and disks to 
 4TB in most cases. The sunlabel(8) format is limited to 2^32-1 sectors 
 per partition and 8 partitions for a total of 16TB. For larger disks, 
 gpt(8) partitions may be used.
