Please tell me, if I got wrong here. For me "Add support to CAM for devices with more than 2^32 blocks. (2TB if you're using 512 byte blocks)." sounds like "if you use double sized blocks you will have double-sized limit with the same number of blocks." And 1kb would extend the 2TB limit to 4TB, what would work for me here. Regards Raphael Beckerhome | help
