Fix 1: Use Another USB Port, Card Reader, or PC

A damaged card reader or USB port may cause the computer to fail to recognize the SD card and mark it as RAW. Therefore, when your SD card becomes RAW, the first thing you should try is the following check: 

⚠️Check physical connections

  • Unlock the SD card and reconnect it. There is a small physical switch on the side of the SD card that locks and unlocks the SD card.
  • Restart your computer and reconnect the SD card. Restarting the computer may resolve many random errors.
  • Remove dust and debris from the SD card or USB port.
  • Try another USB port, or a card reader (if you are using a micro SD card).

Fix 2: Fix RAW SD Card using Error Checking Tool

If there is no problem with the SD card and the physical connection, try the Error Checker tool. Windows provides its own Error Checker tool, which can check for file system errors and fix them on your drive. This section also provides a three-way tool to check and fix SD card errors. 

Tip
If you want to check the SD card in depth or prefer to use a simpler tool, you can choose a third-party SD card checking tool.

First, let's start with the error checking tool that comes with Windows.

Step 1. Connect the RAW SD card to your Windows PC. Then, open File Explorer, right-click on it, and select Properties.

Step 2. In the Properties window, go to the Tools tab and click Check under the Error Checking section.

Step 3. Click Scan Drive to find out the file system error and fix it.

Here is a quick guide on using third-party software to check SD card errors. EaseUS Partition Master can scan the SD card deeply and fix the logical bad sectors and file system errors automatically. Especially for beginners, it's much easier to use.

Step 1. Open EaseUS Partition Master on your computer. Then, locate the disk, right-click the partition you want to check, and choose "Advanced" > "Check File System".

Step 2. In the Check File System window, keep the "Try to fix errors if found" option selected and click "Start".

Step 3. The software will begin checking your partition file system on your disk. When it completes, click "Finish".

This typically fixes a RAW SD card or fixes a RAW external hard drive without formatting.

Fix 3: Fix RAW SD Card using CHKDSK

CHKDSK is a command-line version of the error-checking tool that is more flexible and has a wealth of error-checking options. You will need to connect the RAW SD card to a Windows PC. 

Important
Make sure you are typing the correct command lines to avoid data loss. 

Step 1. Right-click the Start menu and select Terminal (Administrator).

Step 2. type chkdsk H: /f /r or chkdsk H: /f /r /x and press Enter. It will start checking for RAW SD card file system errors and fix them. (Replace Z with the letter of your SD card.)

 

 Notice: 

  • /f - tells it to fix errors on the disk.
  • /r - tells it to locate bad sectors and recover readable information.
  • /x - tells it to force the volume to dismount first if necessary.

Fix 4. Assign a Drive Letter to the RAW SD Card

An SD card may become RAW if it lacks a drive letter. Instead of formatting it, you can choose to assign it a new drive letter to fix this error. Please connect your RAW SD card to a working Windows PC in advance.

Step 2. Right-click on the RAW SD card and select the Change drive letter and path option.
