Accidentally denied access to authenticated users

Hello to all

I hav laptop of toshiba running Windows 8.1. In it there are three drives namely c, e and f. Acidentally i denied acess to authenticated users on drive F. After that I am not able to access the drive. But by clicking properties on F drive I clicked Security tab and then Advanced tab under it I realloted the Authenticated users full access to the drive F.
Now I can access the drive but now the problem arises that I am not able to see the pictures or play the videos or install any software saved in this drive.Whenever I try to play the video etc. message appears either that I have no permission to open this or The file is not accessible i.e. the memory is not accessible where the file is stored.

Kindly help

Hi,
You can try going into security in properties then advanced then at the top there should be "owner" you should change this to your username
I will send you a screenshot if you need it
Thanks,
