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.
What you’re not understanding is how hard it is for an operating system to diagnose a problem with a drive.
You’re expecting from Stream they write a full diagnostics tool so the program can figure out what went wrong, which could range from permission issues or formatting, to failing sectors/drives.
In theory you could make something that works, in reality you’ll be getting false positives, for example: a permission error message while it’s actually a physical write error. The ‘wrong’ message is worse than a ‘vague’ message.
If I can look up what the error was with the disk access, in a log, then steam can do that too. It can parse that, and present it to me. That’s what I expect.
And if that fails, it can at least point me to the correct log.
I can not stress enough that the client tells me nothing:
The only approach I have to solve is, is to use a search engine for “steam disk write error”. That’s it.
