Restore the memory card
Restoring a memory card can be a difficult task, but there are several methods that you can try.
1. Use data recovery software: There are many free and commercial software tools for data recovery from memory cards. Some of the most common examples of such programs are Recuva, PhotoRec, and EaseUS Data Recovery Wizard.
2. Connect the card to the computer via a card reader or USB adapter: If your card has physical damage (such as cracks or broken contacts), the use of special hardware can help repair it or read information from it.
3. Seek professional help: In cases of serious damage to the flash card, it is best to engage experienced data recovery specialists.
The main goal when working with damaged files on an SD/SDHC/CF/xD/MMC/Microdrive/FireWire CompactFlash Card is to save data until it is available after formatting the device, although this is only possible if you use specialized software.
