Fix SanDisk USB Drive Not Recognized Issue

PAGE CONTENT:

SanDisk USB drives are widely used for their reliability and ease of use. However, encountering an issue where the USB drive is not recognized can be frustrating, especially if it contains important data. This article provides a comprehensive guide to diagnosing and resolving the problem step by step.

Why SanDisk USB Drive Can't Be Recognized?

Before fixing the unrecognized SanDisk USB drive, it's important to understand why your SanDisk USB drive might not be recognized:

1. Faulty USB Port or Connection: A damaged or malfunctioning USB port can prevent proper communication between the device and the computer.
2. Outdated or Corrupt USB Drivers: If the drivers required for USB devices are outdated, corrupt, or missing, the drive won't function properly.
3. File System Errors or Corruption: Corrupted file systems due to improper ejection or virus attacks can make the drive unreadable.
4. Power Supply Issues: USB ports with insufficient power may fail to detect high-power devices like flash drives.
5. Hardware Failure: A physically damaged USB drive may not respond, even if connected to a functioning port.
6. Virus or Malware: Malicious software can interfere with the USB drive's functionality, causing it to remain undetected.

How to Fix Unrecognized SanDisk USB Drive?

#1 Preliminary Checks for Fixing SanDisk USB Drive Not Detected

Start with these basic steps to rule out minor issues:

1. Try Another USB Port: Connect the SanDisk drive to a different port. If it works, the original port might be faulty.
2. Test on Another Computer: Plug the drive into another device to confirm whether the issue is with the drive or your computer.
3. Inspect for Physical Damage: Check the drive for visible damage, such as a bent connector or cracked casing.
4. Verify the Connection Cable (if applicable): For drives with detachable cables, ensure the cable is not damaged or loose.

#2 Software-Based Troubleshooting to Fix Unrecognized SanDisk USB Drive

When your SanDisk USB drive isn't recognized, the problem often lies in the system's software configuration or file system errors. Below are detailed steps to address these issues.

1. Update SanDisk USB Drivers

Drivers are essential for communication between the operating system and hardware devices. Outdated or corrupt drivers can prevent the system from detecting your USB drive.

Detailed Steps to Update USB Drivers:

Step 1. Access Device Manager: Choose Device Manager from the menu by pressing Win + X.

Step 2. Locate USB Controllers:

• Make the section on Universal Serial Bus controllers larger.
• Search for any gadget that has a yellow triangle on it, which signifies a problem.

Step 3. Update Drivers:

• Right-click on the USB Root Hub or any listed USB controller.
• Choose "Update driver."

• Select "Automatic Driver Search" to allow Windows to locate the most recent driver.

Alternative Method:

• Visit the SanDisk website or your PC manufacturer's support page.
• Install the most recent drivers for your system after downloading them.

Updating drivers ensures compatibility and can fix USB recognition problems without requiring further steps.

2. Scan for Hardware Changes

Sometimes, your system might fail to detect newly connected devices due to temporary glitches. Scanning for hardware changes forces Windows to recognize new hardware.

Steps to Scan for Hardware Changes:

Step 1. Open Device Manager as explained above.

Step 2. Right-click on your computer's name (listed at the top).

Step 3. Select Scan for hardware changes from the dropdown menu.

Step 4. Wait for the system to identify and initialize any connected USB devices.

This quick method often resolves issues caused by missed hardware detection during startup or device connection.

3. Run Disk Management Tools

If your USB drive is physically connected but still not showing up, it might not have been assigned a drive letter, or it may appear as unallocated in the Disk Management tool.

Steps to Use Disk Management:

Step 1. Choose Disk Management from the menu by pressing Win + X.

Step 2. Look for your USB drive in the list of storage devices.

• If it appears but lacks a drive letter, it will need to be assigned one.
• If it appears as Unallocated, the disk needs to be initialized or formatted.

Assign a Drive Letter:

Step 1. Give the USB disk a right-click.

Step 2. Choose Change Driver Letter and Paths... 

Step 3. Select a letter (such as E:), click Add, and then select OK.

Initialize or Format the Disk:

Step 1. Choose New Simple Volume from the menu when you right-click on the unallocated space.

Step 2. To format the drive and designate a file system (such as NTFS or FAT32), adhere to the wizard. 

This process can resolve cases where the system recognizes the drive but doesn’t allocate it properly for use.

4. Check File System Integrity

File system corruption can occur due to improper ejection, power interruptions, or malware. The CHKDSK utility is a built-in Windows tool to identify and repair such issues.

Steps to Run CHKDSK:

Step 1. Open Command Prompt as Administrator: Press Win + S, type cmd, and select Run as Administrator.

Step 2. Type the Command: chkdsk X: /f (replace X with the letter assigned to your USB drive).

Step 3. Analyze the Output:

• If errors are detected, CHKDSK will attempt to fix them automatically.
• If the tool reports that the drive is write-protected, you may need to remove write protection using additional methods (e.g., registry editor or drive-specific utilities).

CHKDSK is effective for repairing minor to moderate file system issues without formatting the drive, preserving your data.

5. Reinstall USB Controller Drivers

USB controller drivers manage all USB ports on your system. Corrupt drivers can prevent the system from detecting USB devices entirely.

Steps to Reinstall USB Controller Drivers:

Step 1. Open Device Manager.

Step 2. Make the section on Universal Serial Bus controllers larger.

Step 3.  Choose Uninstall device by performing a right-click on each item with the labels USB Root Hub or Host Controller.

Step 4.  Give your computer a restart.

Step 5.  At startup, Windows will restore the required drivers automatically.

If automatic reinstallation doesn't occur, download and install the drivers manually from your PC manufacturer's website.

6. Disable USB Selective Suspend

USB Selective Suspend is a power management feature in Windows designed to conserve energy by suspending idle USB ports. However, it can sometimes interfere with device detection.

Steps to Disable USB Selective Suspend:

Step 1. Open Control Panel and navigate to Power Options.

Step 2. Click on Change plan settings next to your active power plan.

Step 3. Select Change advanced power settings.

Step 4. Expand the USB settings option.

Step 5. Under USB selective suspend setting, change the setting to Disabled for both On battery and Plugged in options.

Step 6. Click Apply and restart your system.

Disabling this feature ensures that your USB ports remain active, eliminating potential interruptions in device recognition.

Advanced Fixes:

If the problem persists, try these advanced troubleshooting methods:

1. Reformat the SanDisk USB Drive

Reformatting the drive can resolve severe file system errors but will erase all data.

Steps to format:

Step 1. Open Disk Management.

Step 2. Right-click the SanDisk drive and select Format.

Step 3. Choose a file system (e.g., NTFS, FAT32, or exFAT).

Step 4. Click OK to proceed.

2. Use Data Recovery Tools to Recover Data from SanDisk USB Drive

If the data is important, use recovery software before formatting.

Step 1. Download and install the reliable SanDisk USB drive data recovery program - Donemax Data Recovery on your computer.

Step 2. Choose the SanDisk USB drive after you open Donemax Data Recovery.

Step 3. Click on Scan button so that Donemax Data Recovery can scan the SanDisk USB drive and find the inaccessible files or lost files.

Step 4. Once the scan gets finished, you can preview the recoverable files. Then select the wanted files, click on Recover button.
