Ditch that card of yours and use another one!

I have had similar results using my 7DII, and only from photos on the CF card. I load them on my laptop using a card reader and when I notice them to be screwed up, I remove the card from the reader OR disconnect the reader from computer and re-connect, and they show up fine. Pins seem fine, I'm suspecting my card or the reader in my case.

I am having the same problem. I will have to go through the suggestions above to see if I can resolve the situation. I have had a dozen or so out of 200 with the above shown image defect. The first thing I will do open the file. Second is try opening with a different computer. Third is do my next shoot with a different memory card. Oh, and I will do a side by side check to compare the RAW to jpeg pictures. I have two memory slots in my camera, use one for RAW and one for jpeg. I will also check to see if the defective ones are on my CF card and my SD card. I will reformat the memory cards. I am not too concerned as I tend to shoot way more pictures then I really need and thus get a lot with no defects. But if the problem gets worse, I guess I will be in trouble. Oh, I can also shoot with three different cameras, a 5d3, a 5d2, and a 20d.

As stated previously, multiple cards and multiple cameras with consistent errors.

Many problems are intermittent, and that makes them hard to pin down. Switching cards would be my first step.

I had a laptop which had a problem similar to that; occasionally a few files would show up as corrupted. Every time I turned it on, a few other files would be corrupted; not long after that, the hard drive quit. I would suggest getting the other laptop or an external hard drive, and start copying everything of value off the old one.

I had a similar problem earlier this month and after updating the video driver the problem has vanished.

I never liked hearing this, and I know you won’t, but it has truly proven to be my problem in one instance. The memory in your computer may have a failing chip. With the error occurring with multiple cards means the corruption is happening on the trip from your card to the hard drive. It isn’t possible for THAT many cards to be bad. It’s possible the hard drive is failing, but it usually happens differently than this. There are diagnostics programs you can run to test your memory if your problem persists. Just expanding your horizons. Good luck!

What are you using to download the cards? An external/accessory card reader? A cable from camera to computer?
When I had similar problem in the past, it was bad connectivity between a card reader and the computer. Out of USB ports, I was using a hub. Removed that and re-connected the card reader directly... problem solved.
Some other corrupted files I've had occasionally were due to a hard drive going bad or in need of defragmentation.
So it might not have anything to do with camera or memory cards. In fact, if you are seeing the problem as you say... with various memory cards and various cameras, it's more likely the card reader or other method you're using to do the downloads, or a software or hardware problem with your computer.

The card reader, external, is my next suspect. I checked and all pins are straight. I purchased a new laptop on Saturday and for the most part have all programs installed. Now I will run around 1,000 shots through the camera and onto the new laptop and see what happens. Will let you know.

I had similar problems after some "expert" said to turn on Use Graphic card in LR preferences. With some older computers this causes the problem. My 2009 iMac no longer is damaging images after turning this option off.

He's baaack...
After much testing with old and new computer, several card readers int and ext, multiple cameras I still get the odd corrupted photo... BUT... if I delete them and re-import them they come in fine. I even went so far as to low level format the main cf card on the computer, format again in the camera, test the card with no errors, re-installed the latest version of Magic Lantern using default settings and still get the odd corrupted file or so I thought...
Last night I was at the work station going through all the 2017 photos and as I came across any corrupted photos I switched from library to develop module and after 2-3 seconds the photo magically corrected itself. I did absolutely nothing but stare at the screen. Out of the 30-40 files only 1 did not recover. However, if I export a file that shows as corrupted it carries the corruption. If it magically corrects itself the export works just fine.
I've seen some weird computer sh&^$ in my day but this takes the cake. I don't use the camera raw "use graphics processor" option as I don't use a separate video card, just the onboard.
So where do I go from here? I've exhausted all the testing and possible solutions and am back at square one. Yes, I can correct the problem after the fact but can't eliminate it at the get go.

Good news to any still watching this thread. I purchased a new 750W power supply which is a step up from the previous 500W and while I was at the store I decided to up my RAM from 8 to 24 Gb just in time for the updated LR Classic. Once installed I went through a big chunk of photos and paused on all that showed the pink meanies, after a second the pink disappeared and we are good to go. Now to go back 6 months and redo all the time-lapses and include the previously pink shots.
The rest of the story... about a year ago the power company told us they were disconnecting the main power on x day. I went around and turned off all the computers, domain servers, printers and UPS's. Once the power was restored I turned everything back on but the domain server did zip. No lights, no sounds, no nuthin.
I figured the power supply had gone bad and I would need a new one BUT the boss, aka wife, put her foot down and said no computer purchases for the entire year. (I do like new toys) So had to put up with manually connecting all network items manually every boot, what a pain. Anyway, with my work horse acting up I had permission for the new PS and figured I'd put the old one in the server which I did. Got it all together and flipped the server switch only to get zip again. WTF?? Went looking to see which power bar the server was connected to and discovered the boss, aka wife, had pulled her trick of pulling out the plug while on vacations and apparently scheduled power disconnections. So a year of all this extra BS all because of a pulled plug. (lesson learned) The network is whole again and the boss, aka wife, has been duly told how much I love her. (what, you think I'm nuts?) Life is good once again.
