Since no recovery tool can guarantee 100% recovery rate for your data on corrupted SD card, it is important to avoid possible data loss.

  • SD cards have a limited life span. In general, a flash card can support approximately 10,000 write/erase operations. So you should get a new card after using the old one for several years.

  • If some photos, videos, or files are really important to you, make an extra copy on your computer. To backup data on computer, you can use AOMEI Backupper, which allows you to set automatic backups or incremental/differential backups to save time and storage.
