I have the weirdest problem. I have WD My passport external hard drive 1TB and I like it. Until a couple of days ago when it started to cause me troubles. I have a good amount of videos on it. I was watching some of them on my laptop, but then came to a couple that wouldn’t play. I thought it’s just these few and kept watching. But there were more. Maybe half of the videos won’t play. I usually use GOM player - it gave me the “find codec” error, but of course, it couldn’t find them. Then I tried with two other players and I was getting an error that the file is corrupt or missing or there are bad sectors. The weird part comes when I try to play those files on my PC - they play no problem. I can’t understand how’s that possible if the file isn’t complete - I thought it shouldn’t be able to play on either of the computers. Both computers run Win7. I tried to unmark the read-only on the HD but it’s marked when I unplug and plug the drive.
It’s all a bit complicated but I hope someone could help me. 
Hi,
The passport is just an storage device, it wont prevent you of playing any particular file.
Have you tried copying the files again to the drive?
