Launch Disk Drill and select the “Byte-to-byte Backup” option in the sidebar. 2. From the list of drives shown in the center, choose the one you want to back up (e.g., a corrupted SD card or a failing HDD). 3. On the right, click the “Create Backup” button. 4. Configure the Backup File. * Name your backup (e.g., DJI_SD_backup.dmg or disk_image.dmg). * Choose the image type (leave it as default unless needed). * Set the destination path. Always save to a different disk than the source. 5. Start the backup process. You'll see a visual progress map: 🟩 Green = good blocks 🟥 Red = problematic sectors (Disk Drill retries reading them later). 6. Depending on drive health and size, this may take time. Disk Drill automatically skips unreadable areas for faster imaging, then revisits bad sectors for recovery attempts. 7. Once the backup completes, disconnect the original storage. Work only with the image from now on. This prevents further damage. *📂 How to Use the Backup for Recovery in Disk Drill* 1. Go to “Storage Devices” in the sidebar. 2.
