Insertion of sd card and some images videos miss8ng S7

[Android Central Question]

Hi. I inserted a new SD card into my S7 phone and moved everything from my camera onto the SD card. There were over 2700 items in camera folder. This took a few hours to transfer. When I woke up in the morning, transfer was complete however the SD folder was only showing 2200 items. When clicking on items, somr were not loading, had an explantion mark or a mountain. Some videos and images were missing. Furthermore, the old camera folder had now gone down to 1900 so even more items were missing. Whilst pocking further, i could see around 5am when image were getting tranferred, some of them were not transferred over as they were grey in the middle I.e. a grey image was placed onto of half the images. I can't see any further items which were downloaded after this time. How can I get these images and videos back

Welcome to Android Central! The SD card could be corrupt, defective, or counterfeit. Install SD Insight to see if the card is genuine or counterfeit. Counterfeit cards are programmed to report more storage than they actually have, and if you try saving more than the card can actually hold, then files can start getting corrupt. (Be aware that SD Insight might not work on all Nougat devices.)

If it's a valid card, then go to Settings>Storage, Unmount the card, remove it, and insert it into your computer. Can the computer read these files? Backup as much as you can right now, then run chkdsk to look for bad sectors: http://forums.androidcentral.com/am...guide-using-chkdsk-fix-corrupted-sd-card.html. If it finds bad sectors, and the photos aren't crucial to save, then go ahead and allow chkdsk to try repairing those sectors. If the photos are really precious, then you'll have to try recovering them using 3rd party software: http://forums.androidcentral.com/am...os/500142-guide-recovering-deleted-files.html


I strongly suggest taking advantage of the Google Photos Auto Backup feature, which can save you these kinds of headaches in the future: https://support.google.com/photos/answer/6193313?hl=en. And don't rely on an SD card as the main storage for anything important. SD cards are inherently unreliable -- even ones from reputable manufacturers.
