Overview on RAW partition and data recovery

What is a RAW partition?

A partition is a section of hard drive, which can be used to store data. A hard drive can be divided into one or more partitions to organize data. When you partition a hard drive, you can select file system for partition such as NTFS, FAT32, exFAT, etc. In Windows, NTFS is the default file system on hard drive, and FAT for removable disks. However, during the process of using storage device, partition may become RAW file system. RAW drive issue can happen to various devices such as hard disk, SD card, external hard drive, USB flash drive, etc.

A RAW drive means the file system of the partition is RAW and it cannot be recognized by operating system. Thus, Windows cannot access and mount the partition properly. The RAW partition reports error message when you try to open it. If you check its status in Disk Management, the file system of this drive is displayed as RAW, unallocated, or uninitialized.

RAW Partition Recovery

Is it possible to recover data from RAW partition?

Fortunately, RAW partition recovery is available, and it can be done by partition recovery software. Why RAW drive recovery is possible? Most often, RAW partition is the result of logical data corruption. All data on the corrupt partition seems to be lost and you will not be able to repair it by assigning a drive letter. Partition can be regarded as a container of data, and the file system is the manager which is responsible for managing data. When the manager is corrupted or missing, operating system gets nowhere to know where the partition is located and how files are stored. Thus, we cannot access the drive anymore. If the RAW drive contains important files for you and you can retrieve these files with the help of partition recovery software. When files are recovered successfully, you can format the RAW partition to get it repaired.


Symptoms of RAW drive issue

RAW drive issue does not always happen, but it brings big trouble once it occurs. It often appears with following symptoms when partition is corrupted or becomes RAW:

  • When you attempt to open the drive in File Explorer, a message would appear saying "Disk is not formatted. The disk in drive G is not formatted. Do you want to format it now?"
  • You need to format the disk in drive J: before you can use it. Do you want to format it?
  • H:\ is not accessible. The parameter is incorrect.
  • This 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.
  • If you run chkdsk for RAW drive, you will receive the error message: The type of the file system is RAW. Chkdsk is not available for RAW drives or Convert is not available for RAW drives, chkdsk reports RAW file system.
  • Location is not available. G:\ 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.
  • Location is not available. H:\ is not accessible. The file or directory is corrupted and unreadable.
  • If you check properties for the drive, you can see the file system is RAW. In some cases, the free space is showing 0 byte in size.

Note: Do NOT format RAW partition even though Windows asks you to do so. Formatting will cause further damage to RAW drive and adds difficulty to RAW partition recovery.

How to recover data from RAW drive using DiskGenius?

Step 1  Connect the disk that contains RAW partition to computer and make sure you can see the drive in either File Explorer or Disk Management.

Note: Formatting or running chkdsk command for the inaccessible drive is of no help in RAW partition recovery, thus you should ignore error messages that Windows prompts to format it.

Step 2  Launch DiskGenius and you can see the RAW drive from the main interface. Select the drive from the drive directory on the left pane and click Files tab on the right pane, and check if lost files can be displayed directly.

In some cases, files and folders in the corrupted drive can be listed by DiskGenius without doing any scanning. If you can see your files, you can copy files to a different drive and get data recovered. If files cannot be displayed in this way, you should move to step 3.

Step 3  Select the RAW drive and choose "Load Current Partition Intelligently" option from Tools menu.

RAW Partition Recovery

This feature is designed to quickly retrieve files from corrupted NTFS partition. When the partition's $MFT part is not damaged that badly, this feature will work as magic. It can load all files in RAW drive within a couple of seconds. Then you can copy all files you need to a different drive.

This function is available for DiskGenius Professional Edition, and you need to register the software to the Professional Edition so as to copy files found by this function.

If "Load Current Partition Intelligently" does not work on your RAW partition, continue with Step 4.

Step 4  Select the corrupted partition again and click File Recovery button. Then click Start button on the Recover Files window.

If you want to try recovering files that had been deleted before the drive got corrupted, you can select option "Recover Deleted Files". This recovery mode will scan and analyze sectors tagged as Free by system, so that deleted files can be found and recovered.

If the RAW drive is damaged quite badly, for example, you performed chkdsk or formatted it, the option "Search For Known File Type" should be selected. This option is able to recover files even when file directory gets damaged. Thus you can find more recoverable files with this option selected.

The software is scanning the RAW partition, and many files have been found and listed in the software. You can stop scanning in advance if wanted files have been found.

Step 5  Preview files to check whether files can be recovered correctly.

DiskGenius supports preview various types of files, including photos, documents (MS Office files, PDF file, TEXT files, etc.), audio and video files. File preview helps to judge if the file is correct and whether it is damaged. Select a file and you can view the file in thumb and hex data in the lower pane; right-click a file and select "Preview" or double-click a file, and you can view the file content in a previewing window which shows file content in its original size, see the picture below.

Step 6  Copy files to a different drive and get files recovered.

Select files and folders you want to restore and right-click on them to select "Copy To". Then you'll be asked to select a location to save these files. You should select or create a folder on a different disk instead of the RAW drive and save recovered files.

Tip: If you are an advanced user, you can try RAW partition recovery manually with the help of Sector Editor.

Why does disk partition become RAW file system?

RAW file system means the drive is not formatted and there is not correct file system on it. Reasons why a partition becomes RAW can be various. Now we sum up the common reasons that could lead to the issue.

  • Disk drive cable issue: In rare circumstances, the RAW drive can be caused by loose or broken cables. For example, the USB cable connecting external hard drive and computer is broken or loose; there will be something wrong during the data transfer and then lead to a damaged partition.
  • Improper shutdown: A sudden power cut such as improper system shutdown while hard drive or other storage media is working threats data security. File system is likely to get damaged during the process and hence result in corrupted partition.
  • Error while changing file system: Since different operating system uses different file system types, many users want to change file system format so that the drive can be used under multiple platforms. Some third-party software is able to change file system without formatting drive, but once error occurs during the converting process, the partition may turn to RAW and inaccessible.
  • Improper operations: Many users do not click the "Safely Remove Hardware and Eject Media" icon before disconnecting USB flash drive, SD card or external hard drive. This is not a good habit, as it is one of the major causes of RAW drive.
  • Bad sectors: If the area of hard drive that stores file system information contains bad sectors, the drive will definitely fail to work properly. The most obvious symptom that shows the disk has bad sectors is that when you click its drive letter in File Explorer, it takes much more longer time to response or even freezes computer. If your drive is suffering from bad sectors, you should backup data as soon as possible.
  • Files system structural damage: As has mentioned above, RAW drive is the result of corrupted or incorrect file system. Thus, if file system structural gets damaged, the drive will turn to inaccessible.
  • Partition table damage: In many cases, the corruption of partition table may also lead to corrupted partition.
  • Virus attack: Virus and malware are widespread throughout the Internet, which accounts for many undesired issues like data loss, system crash, data damage, etc. Virus is destructive software which is able to infect all kinds of storage devices and corrupts file system. The affected drive might be RAW or gets encrypted due to virus. Therefore, users should install anti-virus software and scan computer regularly.
