Prevention is cheaper than repair

There are two possible reasons for the card error:

A.) – From the card reader embedded in the laptop (computer), simply pull from the card slot. This operation is strictly forbidden. On the laptop or computer, next clock in the Taskbar, is a small pop-up menu where you can log out, so we will save the file format from destruction, and the data will remain intact.

B.) – Or there was an error in the boot sector, FAT32 or NTFS, from a SanDisk Micro SD partition. What happens in this case is that the Windows system (Linux) opens the Micro SD card and uses the files, but because of the sudden removal of the "cardreader", the program does not have time to stop the process, so the partition table (FAT32, NTFS) from the card, it is deleted. That is: becomes a RAW file system, and all data is deleted. RAW is a so-called, Gross file system (exited from manufacturing as unformatted) because:

  1. Device partition table (hard disk, USB drive, SanDisk Micro SD Card), still not processed (formatted).
  2. The file system FAT32 or NTFS, due to incorrect connection, has been deleted, so it was restored to factory default Raw.

Three good tips

  1. Save the data stored on the Micro SD card, pictures, music, video, via USB cable, Bluetooth or (if available) online on your computer, and then remove the SanDisk Micro SD card.
  2. If you want to save your data using a card reader embedded in your laptop, or a USB card adapter, disconnect it through the Taskbar, in the small pop-up menu next to the clock, so you can disconnect it in device safety conditions.
  3. When creating and saving text, photo, video files, DO NOT USE ACCENTED LETTERS. In case of deletion, data may be recovered, but recovery programs may not interpret data names, images, or other files that contain accented letters, so you will ignore them, or play them as a useless file.

I have made so
