Memory Card Data Recovery

        Causes of physical failure in SD cards:

1. Increase in bad blocks: As usage time increases, more and more bad blocks may appear in the flash memory units of the SD card. When the number of bad blocks reaches a certain level, it may render the entire SD card unusable.

2. Issues with expanded capacity cards: The use of expanded capacity SD cards (cards that display a larger capacity than their actual storage) can easily lead to failures when data exceeding the actual capacity is written, resulting in the card not being recognized.

3. Solder joint detachment: Collisions or drops can cause solder joints to detach or result in poor soldering, leading to hardware failure.

4. Electrostatic damage: Electrostatic discharge can cause instant damage to the electronic components of the SD card, especially when inserting or removing the card without proper anti-static measures.
