The procedure should look something like this:

/sbin/parted /dev/yourdevice
(parted) mklabel gpt
(parted) print
Disk geometry for /dev/etherd/yourdevice: 0kB - 3001GB
Disk label type: gpt
(parted) mkpart primary 0 3001G
(parted) quit

Now build the filesystem.  I normally use:

mke2fs -j -b 4096 /dev/yourdevice

(tap foot for a few minutes)

Now it should mount normally and you can uncomment out the entry for 
that device in /etc/fstab.

Hope that helps.
