When we encounter data lost because of the damaged SD card, it is recommended to try the professional data recovery software – Renee Undeleter to recover data from the damaged SD card.

As a result, the file system of the SD card will get damaged and the SD card will fail to read or write data. Global Wear Leveling: Utilizes all flash memory in the storage devices and will evenly save data to blocks with low erase count.Īs we can see, for SD card which does not have Wear Leveling, the beginning blocks of the flash memory will easily reach its erase cycles and get damaged. And the static data will be moved to blocks with higher erase counts while the blocks with low erase count will be included in the next write cycles. Static Wear Leveling: Utilizes all good blocks to evenly distribute wear throughout the entire device. And Wear leveling could be divided into 3 different modes:ĭynamic Wear Leveling: Uses the available blocks that are free of data and select the block with the lowest erase count for the next write In other words, Wear Leveling is designed to equalize the use of each block in the flash memory and prevent single block from wearing out or data lost.

Wear Leveling should get each of the blocks to reach its erase endurance and extend the lifespan of the flash device. Wear Leveling will work around the erase cycles by arranging the written data to different blocks so that to avoid specific block exceeding its erase endurance.
