My SD card suddenly stopped showing all my photos and video files on my Mac, and I’m worried I may lose important memories and work files. I need help figuring out the safest way to recover deleted or missing files from an SD card on a Mac without making the problem worse.
I ran into this with a Sony SD card on my Mac. First thing, don’t treat deleted files like they’re dead. A lot of card deletions are only logical. The data often sits there until new shots overwrite it.
Recovery apps exist for a reason. If nothing important has overwritten the card, your odds are still decent.
I’d start with Disk Drill, UFS Explorer, or R-Studio. On Mac, I had the easiest time with Disk Drill. It felt less clunky, and it still handled the job fine. Setup took me a couple minutes. Scan results were easy to sort through. Previews worked, which mattered more than anything else for me. It also picked up RAW photo formats, which saved me a ton of time.
The preview feature is the part I trust most. If a file opens in preview, there’s a good shot the recovered copy will open too. I used this to filter the junk before restoring a huge pile of broken files.
A few things matter more than people think:
Before you scan
Use a proper SD card reader. Don’t leave the card in the camera and plug the camera in. I’ve seen flaky connections ruin long scans. Same with cheap USB hubs. They drop out, the scan stalls, and then you’re stuck starting over.
Keep your Mac awake the whole time. Big cards take a while. If you’re scanning 128GB or 256GB, go do something else and let it finish.
And save recovered files somewhere else. Your Mac’s internal SSD is fine. Another external drive is fine. Do not write recovered files back to the same SD card. That’s how people bury the stuff they were trying to save.
If the card was formatted
I wouldn’t panic yet. A quick format usually wipes file table info, not the photo data itself. I’ve recovered files after a format before. Not every time, but often enough that it’s worth trying.
What hurts your chances fast is this stuff:
- shooting more photos after the deletion
- formatting the card again
- running random “repair” tools first
- messing with the card over and over becasue you hope it fixes itself
What I would do
- Stop using the SD card right now.
- Put it in a card reader and connect it to your Mac.
- Install and open Disk Drill.
- Run a full scan on the card.
- Let the scan finish. Don’t cut it short.
- Preview the files before restoring them.
- Recover everything to your Mac or a different drive.
If you want a free option
PhotoRec is the free one I’d point to first on Mac. It works, but it’s not friendly. You’ll spend more time reading menus and poking through results. Also, recovered files often come back with ugly generic names and no folder layout, which gets old fast if you had a lot of images.
One thing people forget
Check your backups before you spend half the day scanning. I’ve seen people swear the SD card was the only copy, then they look and find the photos already synced to iCloud Photos, Lightroom, Google Photos, or Dropbox. Worth checking first. It takes two minutes and might save you a headache.

If the files went missing without you deleting them, I’d check the card’s file system before I went straight into full recovery. Small difference, big deal.
Open Disk Utility on your Mac. See if the SD card mounts with the right size. If it does, run First Aid once. One time only. If the issue is a damaged directory, First Aid sometimes brings the file list back fast. If it throws errors or the card keeps disconnecting, stop there.
I differ a bit from @mikeappsreviewer on one point. I would not keep retrying scans on a flaky card. Bad cards get worse. Best move is to make a byte-for-byte image of the SD card first, then scan the image, not the card. On Mac, dd in Terminal works if you know what you’re doing. If not, use a tool with backup image support. Disk Drill is decent here becuase it lets you work more safely when the card is unstable.
Extra checks people skip:
- Show hidden files in Finder, Command + Shift + .
- Test the card on another Mac or reader.
- Check if the card turned RAW or ExFAT got corrupted.
- Look in Photos, Lightroom import cache, and iCloud sync folders.
If video files are the main goal, expect mixed results. Photos recover better than big video clips after corruption.
Also, this short guide is worth a look if you want a visual walkthrough for Mac SD card recovery, Mac SD card recovery steps for deleted photos and videos.
First thing, stop mounting it over and over in Finder. That’s where I slightly differ from @mikeappsreviewer and @voyageurdubois. If the card is acting weird, every extra reconnect is just more stress on a possibly failing SD card.
What I’d check before a full recovery run:
- Open System Information on Mac and see if the reader even detects the card properly.
- In Terminal, run
diskutil listand confirm the card shows the expected size. - If it shows up but Finder is blank, the issue may be directory damage, not true deletion.
- If the card is physically flaky, make an image first and work from that copy.
I’m also a little more cautious about First Aid than some people. It can help, but on unstable media it can also make a messy file system messier. If these are irreplaceable files, I’d image first, then test repairs later.
For recovery on macOS, Disk Drill is still one of the more practical options because it handles SD cards well, previews recoverable photos/video, and is easier to sort through than a lot of the nerdier tools. If the files are just “missing” and not heavily overwritten, chances are still decent. For a walkthrough, this easy Disk Drill review and Mac recovery walkthrough is pretty clear.
One more thing people skip: if the card was used in a camera, try reading it on that camera only to verify file presence, not to save or record anything. Some cameras can still see folders macOS ignores. Weird, but it happens.
If the card gets hot, disconnects randomly, or asks to be initialized, stop messing with it. That’s the point where DIY can get sketchy real fast. Recover to another drive, not back to the SD card. Basic stuff, but people still do it and then wonder why the files are toast lol.
