“How do I restore a RAW partition to NTFS?”

“Hello, I am having a Seagate external hard disk of capacity 4TB, with three partitions formatted to be NTFS previously. One week ago, one of the partitions suddenly turned into RAW format. While I cannot access any data stored in it. Or I cannot format the hard drive back to NTFS in Windows. So how do I restore this RAW partition to NTFS, or is there a professional RAW to NTFS converter I can use? Thanks!”

How RAW drive comes?

When a partition/hard drive becomes RAW format, which is not standard file system for operating system, you will be unable to access data inside it. So you might wonder why that happens? Usually, there are 4 main reasons.

1. There are bad sectors in the key area of the hard drive.

2. Format the external drive unsuccessfully.

3. The partition table of the drive is corrupted due to virus and malware attack, or the MBR of this hard drive is damaged.

4. If the access permission to the partition is configured improperly, which is related to local security policies, the partition will be given RAW format too, so as to restrain your access.
