Need help on Steam as client does not see installed games

[gorfias]

I run my games from USB 3.0 external drive.

Yesterday I tried to start a game not realizing the thing was not powered on.

Now all my games think they need to be installed yet the games are on the drive.

Any way to direct the client to see the games?

Never mind, got it. Under settings I can add a number of drives. I included the one that went away that is now back and the games returned. Phew!
