CF card and Streaky video

[blacksocksonly]

Hey Guys, first time ever posting in a forum, I have the 5d mk iii and have been shooting with the raw image setting as of late. If i use the sd card, everything is always fine. When I use the CF card (lexar 64 gb 1066x, or sandisk 32 gb 120 mb/s) everything seems to record ok, and plays back on the camera; but once uploaded to my computer every so many frames you see vertical "streaking". Has anyone else had this problem or know what the cause may be? attached are 2 picture frames from a video, one is what the video should look like, the next shows the vertical streaking that appears. any help is appreciated, thanks.

Defective cf card *reader* when transferring the data off the camera? Try another reader to debug.

Good to know. I've seen this on occasional stills. Strangely enough, also from a 5D Mk III.
