Why your SSD shows RAW?

RAW file system indicates the state of the hard drive that has no or unknown file system. Unlike NTFS, FAT32, and exFAT, data on the drives is unreadable because your Windows can't recognize or read it. Namely, the file system of your hard drive is missing or corrupted.

But what causes your show RAW file system? Generally speaking, the answer depends. We list the possible reasons below.

  • Power failure or unexpected system shutdown or meltdown. 
    A sudden power failure or unexpected system shutdown/meltdown may cause your SSD to stop working or a wrong disconnection of the drive that leads to showing a RAW file system.
  • Your SSD has bad sectors. 
    The bad sector is a cluster of storage on the hard drive that's physically damaged. All information stored in that sector will be lost. The operating system like Windows or Linux will skip it while scanning or reading.
  • Your SSD was formatted or repartitioned incorrectly. 
    If the file system is formatted or repartitioned incorrectly, the operating system can't read or recognize it, so your information cannot be accessed.
  • Virus infection breaks the file system directly. 
    If your SSD has been attacked by a virus or malware, it may lead to improper formatting that results in the RAW file system.
  • Your SSD is physically damaged. 
    When your SSD is physically damaged, it can lead to such an error that it's hardly anything you can do to save your data.

Recover data from SSD with RAW file system

If your SSD shows a RAW file system and can't be fixed by CHKDSK, it indicates your SSD is seriously damaged. And the only way to make your SSD accessible again is to convert the RAW file system to a Windows-supported file system.

That means you need to format the RAW drive, which will delete all the data stored on it, so you need to back up or recover your data before reformatting. We highly recommend you use professional data recovery software, like iBoysoft Data Recovery for Windows.
