On my ICH8R controller I have a 1.5TB partition and it works fine on the latest Ubuntu with stock dmraid packages. Is it possible that you are creating the 875GB partition larger than the device? Try creating a 874GB partition, its possible that you are being affected by the bug phillip was discussing on this list the other week where it actually calculates the device size in a funny way.
