When you plug your SD card, USB flash drive, pen drive or external hard drive into PC, you get disk not formatted or you need to format the disk in drive error. And when you try to run CHKDSK to check and repair the error, you may receive another message saying “This type of file system is RAW. Chkdsk is not available for RAW drives”. When the error occurs, the SD card or any other external USB device has become RAW and inaccessible. To fix the issue, you should convert RAW to FAT32, NTFS or any other file system by formatting. But usually, Windows cannot help you manage this job. You can do this with third-party software, like MiniTool Power Data Recovery.
