If I had a wish for christmas from GabeN or Valve in general, it would be actually meaningful error messages from steam.
If I had two wishes, I would like a community tool to share configs to make games work that require tweaking.
But I’d be very happy if I got better error messages.
Because the link is just a Steam forum search result for “disk write error”. There are over 2000 pages of results. OP doesn’t have a story.
