What is RAW partition?

A partition is a section of a hard drive, which can be used to store data. When you partition a hard drive, you can select a file system for partition such as NTFS, FAT32, exFAT, etc. In Windows, NTFS is the default file system on a hard drive and FAT for removable disks.

However, during the process of using a storage device, a partition may become RAW file system. A RAW partition means a partition with an unknown or unrecognized file system. It often represents that your disk or partition has some logical or physical problems and can't work properly on the operating system.

If Windows operating system cannot recognize the file system of a partition, it won't allow any users to access the stored files on the partition. But how do you know whether your drive has a RAW partition or not? Learning the following symptoms of the RAW drive issue will help you out.

Symptoms of RAW drive issue

The RAW drive problem does not always happen, but it brings big trouble when it occurs. It often appears with the following symptoms if the 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 E: before you can use it. Do you want to format it? 
    You need to format the disk in drive before you can use it
  • The drive is not accessible. The parameter is incorrect.
  • Location is not available. E:\ 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. 
    This volume does not contain a recognized file system
  • If you run chkdsk for the 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 the RAW file system.
  • 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 bytes in size.

When you see those error messages appear on your computer desktop, do not format the RAW partition immediately even though Windows asks you to do so. Since formatting may cause further damage to the RAW drive and add difficulty to RAW partition recovery.

The overview of DiskPart

DiskPart is a powerful built-in command-line utility on Windows 11/10/8/7/Vista/XP/2000. It allows users to manage the partitions both on the computer's internal disk and on external disks.

It's worth mentioning again that any of the methods will delete all saved files on the RAW partition or make files unrecoverable even with data recovery software. Therefore, if you don't have any backups, you'd better restore files from the RAW disk or partition first before attempting to fix the RAW partition.

How to avoid facing a RAW partition again?

Even though RAW data recovery is possible, you should always do whatever you can to avoid ending up with a RAW partition or a RAW drive. Here are some tips to help you:

  • Create backups: Drives can become RAW for a whole number of reasons, and you can't reliably protect yourself against all of them. That's why you should always create backups of important data and keep them somewhere safe—you never know when you'll need them.
  • Avoid pirated software: The internet is full of pirated and shady software applications that are either downright malicious or programmed so poorly that they can cause serious damage. If at all possible, download only reputable software applications from established developers.
  • Be careful when formatting: Always double-check or triple-check which drive you're about to format because a single mistake could cost you all your data. And don't interrupt the reformatting process until it is accomplished.
  • Scan your computer for malware: Malware can cause all kinds of nasty issues, and it might even turn a perfectly working drive into a blank slate. To protect yourself against the latest cyber threats, make sure to have a reliable anti-malware solution installed on your computer, and don't forget to use common sense when browsing the internet and reading email messages.
