EOS 5DS split image with black bar?

[randomuser74]

I've been working with an older Canon 5Ds and when I download the photos I get a couple that look like they are half one image and half another, with a black bar all along the right side (when vertical) or bottom (when horizontal).  They don't show on the camera playback, but just on the computer.  What might be happening?

Sounds like a bad card. Are you using a full size card or micro with adapter?

Full size SD card.  It's brand new as of this weekend.  It's strange because the images look fine on the LCD screen of the camera itself and show up only on the computer's download version.

Did you format it in the camera?

Did the old card do the same thing?

If not present on camera there's corruption during downloading, can be card, cardreader(if used), or USB-cable. Try to change one at a time to find the problem.

Are you shooting RAW images?

With RAW images the camera creates a JPG image and packages it inside the RAW image file when saving to the card. When playback on the camera from the card, this embedded JPG image is used. On your computer the software is interpreting the RAW data and finds a corruption. 

I have seen cases where an image was corrupted such that Photoshop / Lightroom couldn't read it but I could use Canon DPP to open it with no problems, so I used DPP to make a 16-bit TIFF and the worked with that in Lightroom. 

Most likely this is a faulty card issue though.

Yes, I formatted the card.  I put the card into another camera and downloaded the images from there (no card reader) and it uses a different cord with a different connection.  The same images that had that issue downloaded fine onto the computer.  So it appears to be something with the cord or the camera's ability to transfer and not the card itself.  These were jpegs just for some quick tests.  But I plan to do RAW going forward.

I would definitely try to see if the images from the camera on the card are ok, and for that you need a card reader or the cable to connect your EOS 5DS to the computer. Adding a different camera in to download the images adds a level of uncertainty and complexity that is best skipped from this situation.
