When we access hard drive, external hard drive, USB drive, flash drive, SD card, memory card, pen drive, etc. we may get the following message prompts that we cannot access D drive.
Drive X:\ is not accessible. The volume does not contain a recognized file system. Please make sure that all required file system drivers are loaded and that the volume is not corrupted.
Encountering this error message means the drive D has become RAW file system. RAW file system is not really a type of file system but presents a problem of your drive. Our current NTFS/FAT file system has been corrupted, how to fix this error or access data from D drive again? We need the professional partition recovery or repair software to fix RAW file system and change RAW to NTFS/FAT32 file system without data loss.
