Hi, I have a Lacie 2big thunderbolt 8tb hdd, and I would like to use it in windows(through bootcamp) as RAID 0, and therefor I need to partition it to MBR in disk utility, and afterwards to make a dynamic disk in windows, but when I try to choose MBR, under partition in disk utility, I'm not given the choice, I only have the GUID or Apple option, the MBR isn't highlighted, why not?? I've googled almost every page to find an answer, but didn't succeed...:-(
