Sometimes when we try to access hard drive, USB drive or memory card, a popup dialogue box is shown as: "The disk in drive is not formatted. Do you want to format it now?" In this situation, the file system is shown as "RAW" when we check the disk property. If we click "No", the partition cannot be accessed. On contrary, if we click "Yes", of course, we will lose all of the files stored on this partition. Then, you may ask: "Is there any method to rescue this RAW, How to achieve raw recovery operation on Mac?" Here we will provide some information to recover data from raw file system.
