LocalHero1953 Posted November 19, 2023 Share #1 Posted November 19, 2023 Advertisement (gone after registration) Today I accidentally deleted an image from the SD card of my Q2 while viewing it on the rear screen in PLAY mode - while trying to switch off the data bars I pressed the wrong combination of FN button and centre button. It wasn't a world-shattering image, but one I would like to recover. Without taking any other steps, I connected the card via a card reader to my Windows 11 PC and tried Stellar Data Recovery. In its first rapid pass it found three files - none images, nor in the DCIM folder; in a 'deep scan' in found quite a lot of others. None of them were still images - all were video files, also not in the DCIM folder. Stellar Data Recovery has always worked for me before. My images are all DNG. The undeleted images are all there. The card is a Sandisk Extreme Pro 128Gb, UHSII, 300MB/s and never gives me problems. Has anyone else recovered images they have deleted in-camera on a SD card? Does anyone know what in-camera 'deleting' does? AFAIK, in Windows it simply deletes the entry in the FAT, not the file itself, so a data recovery app usually has no trouble recovering the file unless it has been overwritten - even then the 'deep scan' can turn up fragments or recoverable elements.

Was the card near full, and did you take images after you deleted? You are right, when you delete in camera it doesn’t actually delete the image…but it does allow it to be overwritten if space is needed for a new image.

No, the card was only a small fraction full, and I took no images afterwards. I'm puzzled! Edited November 19, 2023 by LocalHero1953 Quote Link to post Share on other sites More sharing options...
jaapv Posted November 19, 2023 Share #4 Posted November 19, 2023 Rescue Pro will recover your file. The only snag is that it may present the file as .tif. If that happens you can rename it to .dng. Otherwise run it through Adobe's DNG converter. Rescue Pro should have been included when you bought your card. 1 1 Quote Link to post Share on other sites More sharing options...

Anbaric Posted November 19, 2023 Share #6 Posted November 19, 2023 (edited) I have successfully recovered files from SD cards with PhotoRec, which is free and Open Source: https://www.cgsecurity.org/wiki/PhotoRec It should handle DNG files correctly: https://www.cgsecurity.org/wiki/File_Formats_Recovered_By_PhotoRec It is primarily a command-line utility, but recent versions also have a Windows GUI, QPhotoRec: https://www.cgsecurity.org/wiki/TestDisk_7.0_Release You can download both versions together with the TestDisk utility here: https://www.cgsecurity.org/wiki/TestDisk_Download Edited November 19, 2023 by Anbaric 1 1 Quote Link to post Share on other sites More sharing options...
orngesunset Posted September 14, 2024 Share #7 Posted September 14, 2024 (edited) Advertisement (gone after registration) Hey! I know it’s been a year, but did you recover your files? I have the same problem, and I was hoping you were able to recover yours. Edited September 14, 2024 by orngesunset Quote Link to post Share on other sites More sharing options...

No. Since then I have discovered that solid state drives (i.e. the sort in a laptop or PC) do not 'just' delete the data entry in the FAT but also, soon after, wipe the file itself. I don't know that SD cards are any different, but I suspect not. Quote Link to post Share on other sites More sharing options...
redrocksjoe Posted September 18, 2024 Share #9 Posted September 18, 2024 I have successfully recovered my Q2 SD card using Foremost in an Ubuntu Linux VM. FWIW, it is quite easy if you are not afraid of the command line. -Joe 1 Quote Link to post Share on other sites More sharing options...
redrocksjoe Posted September 18, 2024 Share #10 Posted September 18, 2024 OK, I'll share a secret; I am a CS prof and can't just leave my above recommendation so unhelpful Below are the steps if you can install Ubuntu or Fedora in a virtual machine (Look at VMWare Fusion, UTM or Virtualbox) to restore files deleted on an SD card. - dnf install foremost (fedora) - apt install foremost (ubuntu) Now you'll insert the SD card and run - dmesg | tail Look for something mounted like /dev/sdb1 or /dev/nvme0 - formost /dev/sdb1 The deleted files will appear in a folder called output.
