Moving Steam games from Win7 to Win 10 - About 50% of my games are re-downloading

I'm quite familiar with the process of moving games from on machine to another without downloading. I've done it a few times now.
I have a windows 7 based rig that has about 230Gig of games installed on an SSD and a HDD.
I added a second SSD and installed windows 10 on it.
I moved all of the games (in the "common" directory) from the old SSD to the HDD so they were all together in one place.
I formatted the the old (Win7) SSD and created the steam/steamapps/common directory and copied all of the games on to it so I have an SSD with the Win10 OS and a second SSD with just the games on it, and a 2TB HDD for backups etc.
I then went through the usual procedure of adding the new steam/steamapps/common directory into the Steam client and reinstalling the games.
About half of them do the check for local content and then install and the other half do the check for local content and then start re-downloading the game again. Typically it would seem to be all of the big games that are doing it like Wolfenstein The New Order, Far Cry 3 and Crysis 2.
On the other hand Half-Life 2, Metro 2033 and Portal 2 and the Talos principal have all reinstalled fine.

Any ideas? perhaps some of my games have corrupted in all the copying. Otherwise I'm going to be test my ISP's fair-usage policy this week!

I had exactly the same, but with 750GB worth of games I was moving to a NAS - I'm also very used to moving games around having had Steam for over 10 years, but this was the first time with a W10 box as when I upgraded from 7 I had Steam + all it's games on a HDD, so it just carried on as it was.

I ended up just re-downloading the lot.

Another peeve is if you have an SSD with 100GB free and copy GTA-V to it from your slow storage (65GB) leaving 35GB free, steam insists on checking for space before checking for existing files - which is very annoying as the space is taken up by the game you want to load a bit faster but not enough to watch another 65GB download...
Corrupted install is possible, though more likely it's just misconfigured paths for the games. Try checking each and every game's install path to make sure you aren't accidentally checking the wrong place (after all, you had two game install locations)

I did a complete reinstall, and i have 0 issues with windows 10. I have not heard many success stories going from windows 7 to windows 10 just by updating, just my 2 cents

Thanks for the suggestions, I've tried everything and I think it must be corruption.
It only seems to have affected Bioshock Infinite, Grid, Crysis 2, Minimum and Far Cry 3.
Its just a shame that's three of the biggest games I have!
 


Do you actually need to download them again? If you're not going to play them now, why not hold off?
