I am a photographer and videographer. I was shooting a small gig at a local bar on my Canon EOS 60D. I needed another SD card that could handle RAW video; one of my good friends said he uses microSD cards a good bit for his video work. I went and bought an Extreme Plus 32GB Red/Gold U3 microSDHC with an SD adapter. I formatted the card, took some photos and video. Everything was fine. I shot the gig.
When I went to export the RAW files to my MacBook Pro, most of my video files and almost 60 of the still shots reported an error message as being corrupt/damaged/unreadable. All files are PERFECT when viewed from the DSLR. When viewed on the computer, damaged still-images show horizontal banding and video files freeze-frame (the audio continues to play fine). I have never dealt with this type of issue, so I have no clue where to start. Is this possibly an issue with the card or my card reader? Could this be resolved with a simple free file recovery program? Any advice is welcome.
since the files show up and work fine on the camera i would suggest connecting the camera with the cable to the computer with the card and see if you can transfer and see the files on the computer. So in that case you can use the camera as a card reader to check if the files are still corrupted or not
There is possibility an issue with the card or card reader, so you should exclude the problem first. Connect SD card with another  well card reader to check whether the file is ok to open. If the problem still exits, then a recovery software is needed. In fact, most of free file recovery program is bundled with spam and useless advertisements.
I’ve had a similar issue with a SanDisk USB drives before. It took me 12 hours to get my files back, partly because of all the complicated and misleading stuff I found on Google. Some articles suggest recovering corrupted files from your device with a recent backup. Well, if I had it, I wouldn’t even have to search Google for a tutorial. Maybe you can check this full guide to resolve the issue at home.
I’ve been there with the corrupt file nightmare, so I get your frustration. Here’s a few things you could try based on my experience and some stuff I’ve picked up from similar issues:
Use the Camera as a Reader: First off, try connecting your Canon EOS 60D directly to your MacBook Pro with a USB cable instead of using the card reader. Sometimes the issue is with the card reader or adapter, not the card itself.
Test with Another Reader: If connecting directly doesn’t work, try a different SD card reader and USB port. Sometimes the simplest solutions are the best.
Recover with Software: If the above methods don’t help, you might need to use photo repair software. Stellar Repair for Photo has been a lifesaver for me in the past. It can fix corrupt images and videos and might help with those horizontal banding issues and freeze-frame videos.
Check for Write Protection: Make sure your SD card isn’t write-protected. There’s usually a tiny switch on the side of the SD card for this.
Try Another Device: Pop your SD card into another camera or device to see if the files read correctly there. It helps rule out if the card is the issue or if it’s something with the camera or MacBook.
Hopefully, one of these suggestions helps get your files back. Let us know how it goes.
Although microSD cards with an adapter can work, they may not be as reliable as full-sized SD cards for professional photography/videography, especially for RAW videos. The adapter may be causing all the problems.
est another SD card reader or use the internal SD card slot if your MacBook has one. And, even though the files are visible on your camera, there might be sectors on the card that are partially corrupt, leading to unreadable files during transfer. Check out this article for SD card recovery and its possible fixes.

I probably would suggest a new card reader. I have a cheap $4 universal and it reads everything fine in testing. Now the old Camera uses the old larger SD cards which should be used instead of using an adapter as some problems have come up here and there.
