Hi Matt, I did small hack to skip is_pte_valid() on efi.c and now I have sdc1 partition listed on /proc/partition, but I hit other issue: ntfs-3g mount userspace tool that comes with Fedora now fails with "Failed to read last sector (7814037100): Invalid argument". I also tried to override disk capacity, but SD driver fails with "Invalid command failure" and "Illegal Request" (I'll investigate it later) Many places rely on disk capacity value, I think emulate Windows behavior for these HDD docks will not be an easy task....
