SD card is widely used in digital camera
and mobile phone, so data loss from SD card becomes a common problem. Data loss
from SD card can be caused by many reasons such as accidentally delete,
mistakenly format, SD card is infected by virus or SD card is corrupted. Today
I would like to tell another reason for data loss from SD card, that is RAW SD
card. As we know a normal file system should be FAT (FAT16 / 32) of NTFS, so
there is something wrong with your SD card if your SD card becomes unreadable due to RAW filesystem.
