External hdd issues

So i accidentally bumped the switch on the power switch and it messed up my files and games that are all on the hard drive. Now it asked me to repair which i did and not a single game will start up without an error and forced signout. I tried deleting a game and redownloading it to the ps4 internal hdd and it wont load and stops at the same spot every time after 3 tries. So i transfered another one over to internal rather than completely redownloading a game amd it still gives the error. But hulu that was on internal the whole time still works but it was the only thing on internal to begin with.
