Grub, EFI and 2.2TB partitions



Hi,

I've got a problem which seems to be related to EFI GPT. I've
installed Fedora 9 to a small PATA hard disk and all is well, but I
then added a 3Ware RAID card containing a 3 Terabyte RAID 0 array.
Upon booting, the 3 Terabyte array gets split into 2 volumes - 1 is
/dev/sdb which is 2.2TB in size and contains /dev/sdb1 which is an EFI
GPT partition, and another which contains the remaining storage and is
/dev/sdc.
I really just wanted one large disk which I will be using as a raw
block device (for various reasons!). i.e. /dev/sdb should be a single
device of 3TB containing no partitioning. On non-EFI motherboards this
works fine. Any ideas as to how I can get the same behaviour on this
EFI-based motherboard?

Here's the relevant bit of output from "fdisk -l".

Thanks, Chris.
