Im trying to do a windows 7 raid 0 install on 3 disk which are 4terabytes each. It worked before on 3 by 1terabyte disk but now its trying to limit me to 2terabyte which l think is a MBR limit than windows limit.

i dont think its windows in this case. the 2TB  MBR limit can be overcome by using GPT. You might want to confirm that you RAID controller supports disks bigger than 2TB even on GPT.

Thanx Tendy, it turned out that even though l used gpt, l needed to format the disks using a provided cd which came with raid card not using a windows 7 install disk plus the eufi bios hav to be enabled or supported by mob
