Noticed something strange about fdisk output.

EXAMPLE 1.
We see nothing out of place here. It displays a warning.

[rondo:rondo]$ sudo fdisk -l /dev/sda
Password:
WARNING: fdisk GPT support is currently new, and therefore in an
experimental phase. Use at your own discretion.

Disk /dev/sda: 64.0 GB, 64023257088 bytes, 125045424 sectors
Units = sectors of 1 * 512 = 512 bytes

EXAMPLE 2.
It says disk label is 'dos', not 'gpt' anymore. What is the GPT "system" of
sdb1 then? And there's no warning now.

[rondo:rondo]$ sudo fdisk -l /dev/sdb

Partition 1 does not start on physical sector boundary.

EXAMPLE 3.
I use parted now instead of fdisk. It says both sda and sdb have GPT labels.

BOTTOM LINE.

Is fdisk lying to me?
