There are many related RAW drive problems and you may encounter such errors reported by Windows:

RAW is not a regular file system type, usually the file system is FAT32, NTFS, NTFS5.

TestDisk is a portable data recovery tool. The tool was designed to help recover lost partitions and or make non bootable disks bootable again. TeskDisk is particularly useful when a system is not bootable because of a virus, software, or human error (accidentally deleting a Partition Table). This tool can fix a partition table, recover a deleted partition, rebuild or recover NTFS, FAT boot sectors, fix MFT, undelete and or copy files from NTFS, FAT, ext2, ext3 partitions.

Is it possible to recover RAW partition with TestDisk? The answer is YES.

8. Select “Write” and press <Enter>.

10. Press <Enter> and close TestDisk. Reboot the computer.
