Can access GPT disk in Ubuntu but cannot in Windows and viceversa

No, both are mbr basic. I think parted Magic cd uses dmraid also, and you can see this disk from gparted in the Parted Magic CD.
Some days ago, I had one of the disks as gpt and although I could not access it from both Windows and Ubuntu at the same time because each OS needed to initialize it, Ubuntu did detect the disk even it was gpt.
It is really strange. I can only think the problem may be of having intalled Ubuntu when only one disk was created. After I installed Ubuntu and Windows, I created this second raid 0 disk from bios, and it is detected by everyone except by Ubuntu.

So both arrays are now under 2TB in size? I think you are suffering from this bug:

If you could test the build in my PPA that should fix it. It should get uploaded to the main archive "soon".

Hi Phillip,

I did as the other guys. Installed your dmraid build, rebooted, and then upgraded libdmraid and a few more packages. Finally it is working fine.

Thanks A LOT!
