parted is capable of printing the GPT information fdisk cannot read the GPT, so will tell you what the MBR table contains. From your output, it seems you are indeed have a GPT. A utility called 'gptsync' may help you if your MBR table doesn't match. It comes with rEFIt, and I know that it is available as a package in Ubuntu, but I am unsure where to obtain it for RH.
