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".
