Glad to see that you eventually worked it out.

Then it is unlikely that you need the 'pata' driver. It is for old 
parallel ATA (aka IDE) drives.

This shows that GRUB can handle 8 TB filesystems and the BIOS is faulty. 
However couldn't you just use a separate RAID array based on small 
partitions located at the beginning of the drives for /boot ?
