Thanks to all of you man! really....

Danny_G & bilbo you guys are right as last night I did it with 1 video.
Meaning I transfered 1 video from my notebooks hard drive to the external one dated it different deleted the video from my notebooks drive and then restored it back and it appeared.

So yeah! the external drive is storing the files in a NBP format since as bilbo stated it don't recognize wmv & or avi formats.

El Gamo thanks for taking the time.

CC's all around.
