I believe ita a GPT http://en.wikipedia.org/wiki/GUID_Partition_Table
Which you can easily do with the standard linux disc tools. In fact you
have to use this type of table for drives over a certain amount of TB.
The only thing that might catch you is that fdisk does not work on GPT
you have to use gdisk instead.

Course with an external drive the question is should you use something
like NTFS in order for the drive to be more universally compatible with
any machine you plug into. As noted on the page I linked, not all
version of Windows support GPT so don't use that if you care about
windows compatibility. For some odd reason MAC doesn't have read/write
NTFS on by default according to some pages:
