Your drive appears to be an HP OEM drive. Firmware is most probably intentionally crippled, since CXM05H1Q is the only firmware mentioned, and other HP OEM drives with the same firmware appear to be missing these additional SMART parameters as well.
You can probably ask the seller to replace yours with a Dell OEM version - the one mentioned earlier in this thread with the CXM03D1Q firmware.
Apparently,
H1Q = HP
D1Q = Dell
