fdisk will tell him that.

With a GPT, fdisk will write something like:

# fdisk -l /dev/sda

WARNING: GPT (GUID Partition Table) detected on '/dev/sda'! The util 
fdisk doesn't support GPT. Use GNU Parted.

Disk /dev/sda: 6301.1 GB, 6301061767168 bytes
255 heads, 63 sectors/track, 766060 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000

    Device Boot      Start         End      Blocks   Id  System
/dev/sda1               1      267350  2147483647+  ee  GPT

So, parted should be used to look at the partitions.
