Many users have encountered a situation that the file format of storage device suddenly becomes RAW in the process of using computer, resulting in disk loss, and they can not see any content. It is said that device has a price but data is priceless. How can we let the unintelligible error destroy our data? This article provides some practical solutions to the problem of storage device partition sudden change, hoping to help you protect your data.

What is a RAW Partition for Hard Drive
In fact, in terms of important data, the best way to save is to take multiple backups and manage them separately. But most ordinary users tend not to have this condition, or the awareness of the backup habit and data protection. When it comes to equipment problems, it is often too late to repent. In the case of the most common ones of disk loss and zero capacity, most of them are caused by the sudden RAW format change of partition.

Fault Phenomenon: File format sudden change is most common in flash drives, phones, tablets and mobile hard drives, followed by PC hard drives. There are many symptoms, and the main performance is as follows:
1. You can't access the pre-set disk, and a single click prompts you to reformat it.

3. Enter the device manager of disk management menu, and you will find that the status of the problematic disk is not available.

Reason of Failure: There are many reasons for the sudden change of file system format, which is mainly divided into the error usage and hardware/software quality. Either way would cause the disk file directory system error.

Errors caused by means of use
1.Without the normal plug and pull of the mobile device, this can lead to a RAW error, as well as an operating system problem.
2.Incomplete read-write operation results in confusion and incompleteness of file directory information.

Problems with hardware and software quality
1. Select inferior hardware products, including inferior power supply, motherboard, data line, especially the inferior external hard drive box.
2. Use the third-party disk partitioning tool. The actual operating system support of such software for Windows Vista is not very good. It is recommended to use the built-in partition tools in Windows.
3. Finally, there are errors caused by system crashes, such as viruses, hard disk hardware failure, or sudden outages during hard disk working period.

Recovery Method: It is suggested to format the partition first and then restore data with data recovery software. It may be useful in some situations, but we don't recommend to handled with this way in all situations. Because after formatting, recovered data directory structure is not complete. Especially for the important files that are often edited, because of more file fragmentation, most of the files are not open.

1. Use Disk Genius to fix RAW Partition
  • Search for lost partition
  • Find the missing partition and keep
  • Search for data within the partition
Principle: When we partition and format the hard disk, as the success creation of partition, partition table will automatically record the following information: primary partitions, extended partition, logical partitions, and partitions that can be used for installation and startup system, etc. If the partition in the hard disk is not corrupted, only the partition table information is wrong, then we can rebuild the partition table by the existing partition.

2. Use RePicvid to Perform Partition Data Recovery
  • Locate the problematic disk
  • Analyze and scan the files in the problematic disk
  • Retrieve the files and save them
Principle: This way bypasses the broken partition table and moves the data directly to another folder. In addition, You can also try this method to get the data back if incorrectly format the problematic disk.

Tips: The unusual RAW partition failure (exclusive for NTFS format) caused by permission settings, Indicates that you have no permissions when opening RAW partition. Just right click the RAW disk, select Property>Security. In the dialog box, remove unwanted users and add your own users. Then change the permissions to administrator.
