EOS Rebel T7 Today's photos vanished from SD card, yesterday's photos OK

[NoelleW]

I took like 20+ photos in the span of an hour or more. When I went to look at them later that day, they were not there. I checked the SD card and it was not locked. I had photos on there from the day before that showed up. I put the SD Card into my computer. I checked for hidden files and downloaded recovery software. Still no photos. SD Card is not bad. It's brand new and saving new photos. It was not full only 1 photo from thr day prior was on otm What could have happened? I have a Canon Rebel T7 camera and ImageMate Pro SanDisk SD Card.

Is this a Micro SD Card in an adapter. Those cause all sorts of problems from cameras locking up. To missing some or all of your pictures. So always stick with Full Sized SD Cards. What capacity is the SD Card? Your camera doesn’t work well with SD Cards larger than 32GB (SDHC). They cause that lineup of cameras to lockup and hang. What brand SD Cards are you using. Where did you purchase them from. Was it a reputable store or website. Amazon or Walmart Marketplace is not a reputable retailer. Anyone can open a storefront and sell counterfeit items. We’ve seen this happen here before on numerous occasions.

ImageMate Pro SanDisk 256GB. It is a micro that goes into the adapter. I think it was purchased at Walmart. It was a gift.

Greetings ,

You'll want to cease using this card with adapter.  As my colleague pointed out they are unreliable, and susceptible to data loss.  Best to go with two or three smaller cards for your camera.

Discontinue using that card as my colleague pointed out. That is most likely the cause of lost images. Use multiple smaller 32GB SD Cards. Your camera doesn’t work well with 64GB or lager (SDXC) SD Cards. So stick with a Full Sized 32GB or smaller (SDHC) SD Cards.

Is there a way to get the photos back?

[deebatman316]

More than likely not. But there are SD Card recovery services that can. I’ve never run into a problem like that before or have had to use any kind of services like that before.

You can try SanDisk Recovery Pro

Inside the package your card came in there's a key to activate the software.  See this knowledge base article for assistance.  Note however, if the photos weren't written to the card there won't be anything to recover.  It won't hurt to try though.

NoelleW, welcome to the site and sorry to hear that you lost images. I would be willing to bet that they didn't vanish, they were never written to the card.

As others have said it would be best to not use Micro cards in your camera, they have known issues. Many of the Micro's don’t fulfill your camera's requirements for speed which can cause performance issues or writing failure.

The physical adapter for the Micro card is an issue when using it in a full-size SD slot. The adapter can be a point of failure if the Micro is not seated properly or moves when you insert it into the camera.

For your EOS Rebel T7 it is suggested that you use SanDisk or Lexar, full-size SD/SDHC/SDXC card. Depending on how much you shoot in a single event it’s best to use a 64GB, 128GB will work and give you additional storage. UHS-I speed, Class 10 is great for performance and should perform without issues. UHS-II I believe is not compatible.

That particular lineup of cameras for some reason doesn’t work well with SDXC SD Cards. They cause the camera to hang and lock for no reason. Using smaller SDHC SD Cards solve these problems.
