Tf2 validating files stuck at 100 fix
Frag at 0%, Running it in Win 8(VHD) Any way to skip it? S:-It is nowhere related to HDD failing in my case, though it might indicate data corruption in your's, see SMART data. You can try defragmenting the game files in Steam through the Local Files tab of Team Fortress 2's Properties page in the Steam Library, but I found using the OS's defragmentation tool was necessary if I recall. You may need to validate files manually after this, but it should hopefully be the last time.
I woke up today and before working, I turned on my computer and checked Steam.
You can do it manually from the properties tab by right clicking in the game list.
If something goes whacky with your game, this sometimes fixes it.
Your statement is very informative, but doesn't necessarily mean that this is not the solution.
As stated, that was my experience and that's what happened.My HDD could have failed for any number of possible reasons, but I have no way to know.
