Step 1: Launch MiniTool Power Data Recovery. On its home window, select the SD card partition and click the Scan button. If the SD card is not detected, click the Refresh button to reload the drive list.

The scan duration depends on how many files are in this SD card. This SD card data recovery software provides options to pause and terminate the scan, but it is not recommended that you stop the scan midway as doing so will result in incomplete scan results.

Step 2: After scanning, you can unfold each folder from the tree structure under Path to find the files you need. Also, if you want to locate the desired files more quickly, you can take advantage of the Type, Filter, and Search features.

By moving on to the Type category list, you can customize which file types to view. For example, if you want to view all videos captured, you can focus on the Audio & Video section.

The Filter feature lets you filter out unwanted files by file type, file size, file modification date, and file category. The Search feature helps you locate a certain file/folder by searching for its name. Partial or complete names are supported, as long as they are consecutive and correct characters.

To ensure that the recovered files are needed and openable, you are supposed to preview them. Supported types of files to preview include PNG, JPG, JPEG, DOC, DOCX, MKV, WEBM, MTS, FLV, 3GP, MP4, and more.

Step 3: Select all the files you want to recover by checking the checkboxes next to them and click Save to choose a safe location to store them.

After rescuing the data, it’s time to format the blank SD card.

You can format the SD card to a FAT32 file system with the help of Windows Explorer.

Step 1: Connect the blank SD card to the computer via a card reader.

Step 2: In File Explorer, go to This PC, then find and right-click the SD card to select the Format option.

Step 3: Select the FAT32 file system, specify a volume label, and then click the Start button.
