Windows 7: WMP 12 does not play video if stored on non-OS hdd

WMP 12 does not play video if stored on non-OS hdd

Anyone have any ideas how I can fix this?

I have a set of h.264 files (mp4). When these videos reside on the C: drive WMP has
no problem playing them/streaming them. But, once I moved them to another internal hard drive, to a non-os drive, and re-add the new folder to WMP library, WMP sees the files but only displays a black screen and plays audio.

Now, please do not go off on a "codec" tangent, because clearly if WMP can play the files if stored on the C: drive it has the codecs to play them.

The reason I need to store the files on a non-os drive is because I just got a new SDD drive that is not large enough to accommodate video files.

I don't believe you have a codec issue either. That's rather some form of rights conflict.
Try to take ownership of the directory and/or the movie clips.

If it was an ownership issue, the audio wouldnt play either. Are you sure the files didnt get corrupted when you moved them off the OS drive? Try copy-pasting again.

Also, can you play the files with VLC or Quicktime?

I don't think they got corrupted because I moved the files to non-os drive and didn't work. Then moved them back again. So a copy from the non-os drive and pasted to the os drive, and worked like a charm. VLC and GOM play the files without issue, both the non-os drive and os-drive files alike.
I will give the ownership option a try and report back.

If VLC and GOM play the files fine, its possibly a WMP quirk. Try this WMP troubleshooting guide.
