So true we lost some good Vns due to data lossThe other big lesson, arguably the even bigger one is this - if you are going to use your PC to earn money, make sure you back up your drive in case of h/w failure.
Honestly, I can never understand why someone would spend tons of $$$ on a video card for rendering, but then leave the storage device, be it HDD or SDD, as a critical single point of failure that could ruin it all. A proper external NAS is cheaper than a good graphics card anyways.
