however in my playthrough Wrex is dead and i did destroy the data. Mordin had figured out the cure anyways and would have gone up the tower had i not convinced him otherwise

Apparently it is impossible to save him if either one of those is done the other way around. I tried everything, checked walkthroughs.Still, saving the Krogan is worth it.
