Recover RAW Drive Data First

Although you are suggested to format your hard drive by Windows, you should know you can't format the RAW partition directly because you still have important files in it. In this case, what should you do to fix raw partition?

Probably you are suggested to fix RAW file system by using CHKDSK. The fact is that you are 90% likely to see the following error message "The type of the file system is RAW. CHKDSK is not available for RAW drives."

So what's the real story? Well, you'd better head to find reliable RAW drive data recovery software to help you in this case.

What is raw drive data recovery software? To put it simply, it is a kind of software that can restore data from RAW internal/external hard drives without bringing any damage. As formatting will delete all data on RAW drives, it is highly recommended for you to extract data or files from the RAW partition before formatting using a professional data restore utility... 

My personal tip is using MiniTool Partition Wizard also, which is really a great solution when you are faced with RAW hard drive recovery issue. In my experience, it works great on blank SD cardUSB data recovery, deleted files recovery, and more. In short, it is read-only software when performing RAW drive data recovery.

Tip: Without a readable file system, RAW drive is displayed as Unidentified in this case.

Step 2. Data Recovery will quickly scan the drive and list all partitions it has found (Each time at most 10 partitions are displayed. If these partitions do not offer files you need, click Show More Partitions to select other partitions for a check.). Then you just unfold each partition to check the file, select the ones you need and click Save button to save the needed files to a safe location (should be different from the original data location).

Tip: For a quick check, you can make use of the Filter feature. By selecting the file extensions, only the desired files will be displayed in the middle window. Besides, Preview is very useful for image browsing.

Hence, it has gradually become the tendency of today's file system.

How can you easily convert RAW to NTFS? In fact, there is no real RAW file system converter, but formatting can help you get rid of this issue. (Since you already saved data in the RAW drive, you don't need to worry about formatting.)

For Your Info: Reasons for Hard Disk Became RAW

Knowing how to deal with "hard disk partition became RAW", I want to share the reasons for hard drive became RAW. RAW drive can be caused by a number of reasons such as virus infection, format failure, accidental shutdown, power outages, etc. Here I will expose 6 primary reasons for this issue, hoping they can help you avoid RAW drives.

  1. Bad Sectors: If there are bad sectors in the key area of the hard drive, the hard drive will definitely work abnormally, and RAW file system is one of the many phenomena.
  2. File System Structural Damage: As we all know, RAW hard drive is surely involved with RAW file system. Hence, if the file system suffers structural damage, hard disk partition may become RAW.
  3. Partition Table Corruption: If the partition table of the drive is corrupted, the hard drive may become RAW drive. What caused partition table corruption? Failed disk conversion, file system damage, hard disk failures, etc. are the main causes.
  4. Power Outage: If power outage happens, hard drive is likely to go wrong, leading to many hard drive issues including partition loss and RAW file system.
  5. Virus/Malware Attack: Virus attack or malware attack can damage the partition table that carries the partition information. Partitions that suffered from virus/malware attack can easily become RAW. Hence, it is better for you to run anti-virus software regularly.
  6. Improper Operations: Also, if you unplug an external hard drive or USB drive without selecting "safely remove hardware and eject media" option while the drive is still performing disk I/O operation, probably you will get a RAW drive.
