1. SanDisk SD Says RAW File System
You see this error often when clicking Properties of the card. To know what RAW file system is, it is necessary to know the concept of file system. Simply, file system can be compared to a library. Data block group is shelf in the library, on which there are many books. Those books can be considered as data block. Every book is usually located in a certain place on the shelf, so you can find the book as long as you know which location you put it on. If file system is corrupted and shows RAW, system cannot find the location to store your data. Therefore, you cannot access your card that says RAW.
2. SanDisk SD Card 0 Byte
Similarly, if library is closed, you cannot access it to get any book. When system is corrupted turning to RAW, Windows cannot read any data from it and detects it as 0 byte.
