Differences between Formatting and Clearing Data on A SD Card

If we want to clear all data on a SD card, we usually perform quick format on the card. Yet, this way can only remove the file allocation table and cheat the operating system that there is no data on the SD card. In fact, the data is never cleared. In this situation, we can use a data recovery application to recover the data.
Low-level formatting, also known as zero-filling, can modify each readable block to be “0”. This process will completely wipe a SD card and return it to the pristine state.
Therefore, how to irrecoverably clear data on a SD card? A professional low-formatting tool works. Once a SD card goes through low-level formatting, the SD card will be erased completely, unable to be recovered any more.
