Part 1: What is a RAW File System?

Before getting straight on how to fix the type of the file system is RAW error, it's essential to first understand what a RAW file system is.

A RAW file system is distinct from standard file systems like FAT and NTFS, as it lacks recognition by Windows and other operating systems. This issue is pervasive and can affect various storage devices, including USB flash drives, memory cards, and computer hard drives.

The consequence of a file system transitioning to RAW is the inaccessibility of the data it contains, leading to a vexing situation. Several error messages or symptoms often accompany this issue, such as:

  • Windows Disk Format Prompt: An attempt to open a RAW file system drive in Windows File Explorer may trigger a message suggesting the need to format the disk before use.
  • 0 Bytes in Drive Properties: The drive properties will reveal both used space and free space as 0 bytes, and the file system will be labeled as RAW or unspecified.
  • "Not Accessible" Error: Efforts to access the drive can result in an error message, such as "Drive: \ not accessible. The file or directory is corrupted and unreadable."
  • CHKDSK Error: Running the Windows Check Disk utility (CHKDSK) on a RAW hard drive yields a message indicating, "The type of the file system is RAW. CHKDSK is not available for RAW drives" or "CHKDSK the type of file system is RAW."

These symptoms collectively signal a substantial problem with the file system on your storage device.

Part 2: Causes of the RAW File System

One of the primary reasons for a RAW file system is file system corruption. This can occur due to various factors, including unexpected system shutdowns, power failures, improper ejections of storage devices, or software issues.

When the file system gets damaged, it can no longer be recognized by the operating system, leading to the RAW state.

2. Physical Damage to the Storage Device:

Physical damage to a storage device, such as a hard drive or a memory card, can result in bad sectors or other issues that render parts of the file system unreadable. If critical areas of the file system become damaged, the entire file system may appear as RAW.

Physical damage can be caused by drops, impacts, exposure to extreme temperatures, or manufacturing defects.

3. Virus or Malware Infections:

Some malicious software, including viruses and malware, can target and corrupt the file system. These infections may manipulate or damage the file system's structure, resulting in the RAW state. It's crucial to have updated antivirus software to help prevent such issues and regularly scan your storage devices for malware.

4. Other Factors:

While these are the most common causes of a RAW file system, other factors like file system format errors, operating system issues, or hardware problems can also contribute to this problem. For instance, improperly removing a storage device without ejecting it safely can lead to file system errors.
