Why Files Get Deleted/Corrupted After Moving to SD Card?
If you like to transfer Android data to SD card to make a backup or enlarge the storage space, you might have met the problem that the synced files are deleted or damaged in SD card. Do you know the reason for the issue? If not, just let this article tells you why files get deleted/corrupted after moving to SD card and how to settle the issue.
In this case, data would be deleted or corrupted for several reasons:
- SD card is inserted improperly. When your SD card is placed unsuitably, the device will not be able to detect the card and the data saved in it.
- The amount of the transferring data is too large. If you sync too many files at one time, the transmission between the device and SD card would be interrupted or failed due to the heavy load.
- Some applications on your phone are incompatible with the device. The troublesome applications will affect the smooth running of your phone as well as the SD card on your phone so the files would be damaged during the transferring process.
- System crash. A sudden crash of system when the SD card is connected to transfer files can cause the corruption.
Then how can we fix this issue and return the device and SD card to the normal status? Here are some common but useful tips for you.

Just make sure that the card is placed at the right place and check whether the files are corrupted or deleted.
2. Repair corrupted SD card
If the SD card is inserted well but still files on it are still deleted or damaged, the card might be broken. Then, to solve this problem, you need to format the SD card on your phone or with computer. But if this means fails, your SD might be damaged too badly to be repaired so you need to use a new card in this case.
3. Remove Nomedia files
What is a Nomedia file? It is a file stored on an Android phone or SD card connected to an Android device. With it, the players won't scan the card so your files on SD card are hidden under this circumstance.

4. Reduce the work load
Some users might select to transfer a lot of files from Android internal memory to SD card at a time. Superficially, this would be effective cause it can be completed with one simple click. But it is not the right way actually- it would cost more time and sometimes the work load is too heavy for both the phone and SD card and lead to some issues. Therefore, you are advised to transfer the files several times.
5. Uninstall problematic software
Since an incompatible software would cause the error as well, you can try to uninstall the application that you have installed recently to fix the problem. You can simply go to Google Play Store to find out the App and then uninstall. After that, just try to move the Android files to SD card again to see if it is successful this time.
