SD card RAW problem occurs quite frequently due to lots of reasons. If an SD
card has RAW file system, you may run in to big trouble. For example, you may not be able to
access data on the SD memory card. You may not be able to writ other data to
the SD card. Even if you can open the SD card, you may find it shown as empty
one. You can buy a new SD card instead of the RAW one, but you cannot buy the
unique data on the card.
