File access on WD Mybook 3Tb USB3

As every 01/01, i re-installed windows 7 on a blank HD in my desktop.

After everything was ready to use, I wanted to look at one of my videos stored on the HD

All the files are there but when I tried to open them, ther’es a security problem.

I don’t have access to the fles

When I look at the file prperties/security I can see this :

Users or Users groups:

System

S–5-21-145612079-1254861888-2937162222-1000

S–5-21-145612079-1254861888-2937162222-1009

Nothing else!!!

If I want to see the video, I have to change the security options for each and every file.

I’ve have undreds of them and I don’t want to sped days doing it.

Could anbody help me?

Thanks
