Today, I faced a strange problem. I copied personal video files from my friend's laptop into a USB pen drive. The problem is with playing those video files on my computer. None of them are playable on my PC. Both VLC and Windows Media Player failed to play them. Is there any problem with playing vid...

Yes, I checked it on my friend's laptop. No luck. It is grayed out on his laptop also.

I have been facing a strange problem with one USB storage for the past week. This USB drive shows as gray when I connect it to my Windows Laptop. I cannot click on it or open it. Why did a USB Drive get grayed?
