Hello everyone,

Been a while since I posted, and not entirely sure where to inquire about this so please let me know if this is not the correct form!

I had a shoot this past weekend and when I sat down to work on them, I noticed that there were 10 images out of the 646 that were corrupted. Couple examples are below, they come in all different shapes and sizes.

Any idea what happened and how it can be prevented?

Shooting on Canon 6D in RAW. Any help would be much appreciated!

Thanks!

Those are usually corrupt files. Most commonly a memory card failing or a bad card reader.

Try to download using a different method. Try another card reader or connect directly to the computer with the USB cord. Of course, it is possible the files are simply corrupted. If that is so, about all you can do is just don't use that card again.

Does the TF actually know about the soda cans and PVC pipe from 30 years ago?

I once had this simmilar effect when I used a cheap USB card reader.
I bought a USB card reader from a well known brand and did not use that particular CF card anymore.
Never had this effect thereafter.

I had this happen as well. My issue is my iMac. I downloaded same card to my laptop and images were fine. I will be taking iMac in this week to get fixed and can let you know what the outcome is.

Test your memory cards using this software (external link). It's likely cards, but could be camera, cables, PC memory, PC motherboard, PC hard drive, etc.

I had this happen last month. In my case it turned out to be bad ram. Memtest cleared the mystery up real fast! Here is the thread on it:

Once I replaced the ram I reloaded the corrpt RAWs into lightroom and all was well.

Memtest doesn't find all memory errors. HCI Memtest found an error with my RAM that Memtest couldn't. I ran 7 instances for 20 hours to find the problem.

My take is your have a bad memory card. this issue can induce by a bad reader, but the funcdamanetal if the card isn't in its optimal shape to begin with. Since cards are cheap these day, I will suggest replace it. If it is one of those bigger brand, they may replace it under warranty too
