it also applies to 3TB drive with 3TB partition, such as you typically 
use with LVM.

I don't like using raw disk devices in most cases as they aren't labeled 
so its impossible to figure out whats on them at some later date.

just use the gpt partitioning tools and you'll be fine.   as long as its 
not the boot device, the BIOS doesn't even need to know about GPT.

|parted /dev/sdb ||"mklabel gpt"|
|parted -a none /dev/sdb ||"mkpart primary 512s -1s"


that creates a single /dev/sdb1 partition using the whole drive starting 
at the 256kB boundary (which should be a nice round place on most raid, 
SSD, etc... the defaults are awful, the start sector is at an odd location)
