You can learn how to fix RAW hard drive to NTFS in a success from this pose, if you encounter the situation that your external/portable/USB hard drive becomes RAW unexpected.
Scenario: Hard drive becomes RAW format
“My 320GB WD external hard drive works properly, but I want to delete all partitions there and create a new big one. I connected it to my Windows 7 and it is recognized as usual. In Disk Management I deleted all existing partitions and it shows up as Unallocated. Then I right-click the unallocated space to create a new simple volume. I initialized to MBR and I started to format the HDD with normal format (not Quick Format).
Nevertheless, it says it is formatting but there is no % process appearing. Around four hours or so, it still shows no progress. I canceled it by restarting my computer and the hard drive has become RAW. Helpless! Any suggestions on how to fix RAW hard drive to NTFS or other readable formats under Windows will be appreciated.”
It is a post about an external hard drive becoming RAW after unsuccessful formatting. Actually, the same problem also happens on a portable hard drive, USB hard drive, flash drive, micro SD card, and even internal hard drive sometimes. If you run CHKDSK /f on the RAW format drive, chances are that you’ll get this error message: CHKDSK cannot be run on the drive. The type of file system is RAW. CHKDSK is not available for RAW drives. Well, what is a RAW format hard drive, and why does it emerge?
The possible reasons of RAW format
A RAW format hard drive refers to a drive that has not been formatted to any readable file system such as NTFS, FAT32, exFAT, FAT, Ext2, Ext3, etc. Data on that drive cannot be readable because Windows does not know how to access it. Say it plainly, that drive is corrupted or lost. The commonly seen symptoms would be: Disk not formatted, incorrect parameter, or Sector not found, even though the drive shows up as Local Drive and Healthy in Windows.
What caused the RAW format problem? In fact, the answer depends. Generally speaking, the following reasons may account for why the hard drive switched from NTFS to RAW:
• Format suspended
Formatting is the process of preparing a storage device, such as a hard drive or memory card, for use by erasing all existing data and setting up the necessary file structure. When "format suspended" appears, it indicates that the formatting process was halted before it finished, possibly due to an interruption, error, or user intervention.
• Unexpected system shutdown or meltdown
System error or hard disk error has the same bad effect. It can disrupt the ongoing data write operations. If critical file system data structures were in the process of being updated at the time of the shutdown, it can lead to RAW. Also, sudden shutdowns or meltdowns can damage the file system structures that keep track of the location of files and their metadata. Without these structures, the operating system can't understand how data is organized on the drive, and it may treat it as RAW.
• Virus infection breaks the file system directly
Certain types of viruses and malware can target and corrupt the file system on your storage drive. They might alter or delete critical file system structures and data, making it difficult for the operating system to recognize the drive's file system. This can result in the drive being displayed as RAW.
• Inappropriate computer behaviors like unplugging the drive without rejecting it
When you unplug the drive prematurely, you interrupt these ongoing write operations. This can lead to incomplete writes, where the file system metadata or other critical data structures are not properly updated on the drive. In addition, the operating system may no longer be able to understand the file system on the drive, leading to it being recognized as RAW.
• Power failure
Suddenly power outage may cause an abrupt cut off of the electricity supply to your computer or external storage devices, such as hard drives or USB drives. Suppose your computer was in the middle of writing data to the storage device. In that case, the write operations may be left incomplete and the operating system may no longer recognize the file system, causing it to appear as RAW.
Surely, there are other possible reasons that can lead to hard drive partition corruption and change NTFS to RAW. However, it is more important to figure out how to convert RAW hard drive to NTFS or other file systems.

select disk n (where n is the RAW hard drive)
attributes disk clear readonly
create partition primary

Further tips: Recover data after formatting RAW drive
When you format a storage device like a hard disk, SSD, USB drive, or memory card, you essentially reset the file system on that device. This action wipes out the file index, rendering the data on the device temporarily inaccessible to the operating system.
It's important to note that the actual data is still present on the storage medium until new data replaces it. However, this fact often goes unnoticed by most users, leading to confusion and distress when they believe their data is permanently lost due to formatting, especially if they haven't backed up their files.
So, if you want to try to recover your formatted RAW drive, you can try the "Recover Data" function carried on AOMEI Partition Assistant after you upgrade to the Professional edition. It can recover 200+ types of files on HDDs, SSDs, USB drives, and SD cards.
Step 1. Install and launch AOMEI software. In the Main Tab, click on "Recover" > "Recover Data".
Step 2. The Recover Windows Data tool will appear. Choose the partition location to initiate data recovery and click on "Start Scan".
Step 3. Once the scan is complete, you'll find all deleted files, recycle bin contents, and other missing files displayed. Select the files you wish to recover and then click "Recover files".
Step 4. Next, select a folder path on your PC to save the recovered files. The choice of where to find deleted files on the computer is entirely up to you.
Step 5. Upon successful recovery, head to the path you selected to access and view your recovered files.
The above solutions on how to fix RAW hard drive to NTFS actually point out how to format RAW hard drive to NTFS file system successfully. No matter Diskpart in Windows, Disk Management, or the third-party software AOMEI Partition Assistant, the purpose is to make the RAW drive usable again. After performing hard drive formatting, you can move OS to a new drive or copy partition to a new disk to store data.
