I have Windows 7 using an LSI 3Ware 9650SE-8LPML with 4 of the WD Green 2TB drives. I've done a bunch of reading on this; I'm not using it as a boot, and the array has no data; it can be deleted and recreated any way necessary.

When i make the raid 5 array in the 3ware bios, the resulting 5.6-ishTB of space is correct. Upon entering diskpart.exe OR windows storage "disk management", the un-initialized disk shows only 2048GB of space.

Doesn't matter if I pick MBR (wrong) or GPT (which is what it should be), the resulting disk is 2048GB and cannot be formatted any larger.

What am I missing? Is this possible to have all 5.6ish TB as a single, add-on drive letter for storage? (not booting!)
