How to Fix RAW SD Card Without Formatting

💡 This article is written by humans, with all solutions and steps verified.

SD cards are small and can store data for extended periods without an external power source, making them common in electronic devices such as cameras, drones, and dashcams. Because of this characteristic, they are more prone to failure than hard drives. A common symptom is that accessing the SD card on a computer prompts you to format it, and right-clicking to view its properties shows the file system as "RAW".

In this case, formatting may seem like the fastest solution, but it will erase all photos and videos in the SD card. Do you want to fix a RAW SD card without formatting? This guide is what you need. Besides, we will explain the details of the RAW file system and its causes.

Why Does Your SD Card File System Become RAW And Prompt You to Format It Before Use?

In normal situations, FAT32 and exFAT are common file systems for the SD card, which are mainly used to organize and manage data to facilitate efficient access by operating systems and applications.

However, when the file system is corrupted or unreadable, Windows will mark it as "RAW" to let you know its status. Simply put, RAW is not a true file system but rather an error state telling you it lacks a recognizable file system for the SD card. Because of the built-in error-correction mechanism in the operating system, when this occurs, you will be prompted to format the SD card to restore its usability. Usually, it is caused by the following reasons:

Two Things You Must Do Before RAW SD Card Repair

1. Check the Connection

As mentioned above, sometimes the SD card file system displaying as "RAW" might be caused by a connection or card reader issue. Therefore, before getting down to the solution, you should first try connecting it to a different USB port or using a different card reader. If it is possible, connect it to another computer or device.

2. Rescue Important Data on the SD Card

After ruling out a connection issue, it is confirmed that the RAW is caused by a file system failure, such as the file allocation table, partition table, or directory index. These logical errors only prevent you from accessing the files directly. These files are still intact in the SD card sectors. Directly performing a RAW micro SD card fix will cause files to be severely damaged or permanently lost. Therefore, recovering them is the top priority.

Here, we suggest you use iBeesoft Free Data Recovery, which is easy to use, and the deep scan mode can skip damaged file systems to extract recoverable data fragments. This is especially helpful for storing video and photo files that were stored in consecutive segments.

Here are the steps for using iBeesoft Free Data Recovery to recover data from a RAW SD card for free. Before starting, please connect it to your computer first.

  1. After downloading and installing iBeesoft Free Data Recovery, launch it.
  2. Select the SD card with a RAW file system, and then click the "Scan" button while hovering the mouse over the drive area in iBeesoft Free Data Recovery.
  3. iBeesoft Free Data Recovery will automatically perform a quick scan and a deep scan. When it finishes, you can see all recoverable files on the SD card.
  4. Tick the checkbox in front of the file(s) you need, then click "Recover" in the lower right corner of the page. Choose a folder to save them on your computer.

Note: If you want to get the SD card working right away, you can skip the repair methods below and format it to a file system Windows can recognize directly. However, before starting, please make sure all your data has been successfully recovered.

How to Fix a RAW SD Card Without Formatting

Once all important files on the RAW SD card have been recovered, you will no longer have to worry about fixing this error. Here, we recommend starting with the first method to ensure you don't miss any useful solutions.

Method 1. Use Windows Error Checking Tool

Unlike other applications, Windows Error Checking is integrated into the "Tools" tab as a supplementary feature for disk maintenance, yet it is still very useful for fixing RAW SD card file system errors such as corrupted file directory structures, inconsistent metadata, and incorrect partition table identifiers.

  1. Open File Explorer.
  2. Find your RAW SD card and right-click to select "Properties" from the menu.
  3. Switch to the "Tools" tab and click the "Check" button under the "Error Checking" option.
  4. In the new dialog box, click "Scan drive" to check for any possible file system errors. Windows will ask you whether you want to repair the errors; if there are, please select "Repair drive."

Method 2. Run CHKDSK

Simply put, CHKDSK is a supplement to the Error Checking tools mentioned above. You can use it to fix more complex logical errors by combining different commands. For example, "/r, find bad sectors on the SD card and recover any readable information." The command is especially useful if you want to repair a RAW SD card without formatting.

  1. Press Win + X keys, and then select "Terminal (Admin)" from the menu. If your Windows is Windows 10 or earlier, select "PowerShell (Admin)".
  2. In the command prompt, type in "chkdsk [RAW SD card drive letter]: /f /r /x" and press Enter.

The tool will begin to scan the SD card for file system errors and bad sectors. Once complete, chkdsk will display a summary of the scan results and the repair performed. If you see the message "CHKDSK Is Not Available for RAW Drives," please try the following methods.

Method 3. Advanced Repair from Third-Party Tools

If the Windows built-in tools fail to fix the RAW SD card, it means the file system is severely corrupted. Therefore, using professional repair tools is your priority. Professional tools are more powerful and comprehensive. If you have never used any such tool before, try the following two first.

Option 1. iBeesoft Disk Partition Wizard

Option 2. TestDisk

TestDisk is a well-known open-source data recovery program. It is primarily designed to recover lost disk partitions and repair storage devices that are inaccessible due to corrupted boot sectors. Coincidentally, this is also one of the reasons that causes the SD card file system to be RAW. Although TestDisk can look a bit complicated due to the lack of a graphical interface, you can still repair a RAW SD card without formatting by following the steps below.

  5. Select the partition table type for the SD card. Usually, the default is fine.
  6. Select "Analyze" and press Enter to examine the current partition structure.
  7. Select "Quick Search" to continue. If no partition table is available, select "Deep Search."
  8. Select the missing partition and press Enter.
