considering the amount of worlds colonised, this occurrence happening on most of them is defeated by the fluff. actually considering how many worlds have been settled by man, i don't even think warp storms were a common occurrence. these were big events. that said, i can't pretend to be a warp storm expert. once their descendents died out? ppl do pass on knowledge. we've been doing it as a species pretty consistently.
The human race colonised the majority of the Galaxy during the 'Golden Age of Technology' (later known as the 'Dark Age of Technology' during the Age the Imperium). This was the utopian sci-fi age. Everything was going fine until the Fall of the Eldar and the birth of Slaanesh, which gave rise to the Eye of Terror, and spread warp storms throughout almost the entire galaxy, making warp travel almost impossible and cutting off nearly every system from every other. Heck, it even made it impossible to travel from Earth to Mars, and they're in the same system! This caused several millennia of wars called the Age of Strife. Many human worlds, including Earth, were reduced to a dark-age state, and it took several thousand years for them to progress back to space flight etc, once the warp storms subsided. Pre-unification Terra was ravaged by nuclear, biological and chemical warfare for hundreds of years.
Of course people pass on knowledge, but if you store it all in computers, and then there's a nuclear war and all the computers stop working, you're stuck with pretty much nothing.
