Solving the “USB Storage Device Not Connected” Error on PS4

If you’ve encountered the frustrating “USB storage device is not connected” error on your PlayStation 4, you’re not alone. This common issue can prevent you from using external storage, backing up your data, or installing system updates. In this comprehensive guide, we’ll explore the causes of this error and provide step-by-step solutions to get your USB storage working with your PS4 again.

Understanding PS4 USB Compatibility

Before diving into troubleshooting, it’s essential to understand what your PS4 requires from a USB storage device:

• File Systems: The PS4 only supports FAT32 and exFAT file systems. NTFS-formatted drives will not be recognized. If you need to convert your drive, learn how to change exFAT to FAT32.
• USB Version: For optimal performance, use USB 3.0 or later devices.
• Storage Capacity: The PS4 supports USB drives with a capacity between 250GB and 8TB for extended storage.

Ensuring your USB device meets these criteria is the first step in resolving connection issues.

Common Causes of the “USB Storage Device Not Connected” Error

Several factors can lead to this error:

1. Incompatible File System: If your USB drive is formatted with NTFS or another unsupported file system, the PS4 won’t recognize it.
2. Hardware Issues: Damaged USB ports, faulty cables, or malfunctioning USB drives can prevent proper connection. Sometimes, you might encounter the “A device attached to the system is not functioning” error.
3. Outdated System Software: Running an old version of the PS4 system software can cause compatibility problems with USB devices.
4. Power Supply Problems: Insufficient power to the USB ports can result in connection failures.

Troubleshooting Steps

Let’s walk through the process of resolving this error:

1. Check and Format Your USB Drive

First, ensure your USB drive is properly formatted:

1. Connect the USB drive to a computer.
2. Open File Explorer (Windows) or Finder (Mac).
3. Right-click on the USB drive and select “Properties” to check the current file system.
4. If it’s not FAT32 or exFAT, you’ll need to format it:
   • Right-click the drive and select “Format.”
   • Choose FAT32 for drives under 32GB, or exFAT for larger drives.
   • Click “Start” to begin formatting (note: this will erase all data on the drive).

2. Update Your PS4 System Software

Keeping your PS4 updated is crucial for maintaining compatibility:

1. Go to Settings > System Software Update.
2. If an update is available, follow the on-screen instructions to install it.
3. If you can’t update via the internet, you can use a USB drive:
   • Visit the PlayStation website and download the latest update file.
   • Create a folder named “PS4” on your USB drive, and inside it, create another folder named “UPDATE“.
   • Copy the update file (named PS4UPDATE.PUP) into the UPDATE folder.
   • Connect the USB drive to your PS4 and install the update from Safe Mode.

3. Test Different USB Ports and Cables

If formatting and updating don’t solve the issue:

1. Try connecting your USB drive to a different port on the PS4.
2. Use a different USB cable if possible.
3. Test the USB drive on another device to ensure it’s functioning correctly.
4. Consider using a PS4 USB hub to expand your connection options.

4. Restart Your PS4 and Rebuild the Database

Sometimes, a simple restart or database rebuild can resolve USB recognition issues:

1. To restart: Hold the power button until you hear two beeps, then unplug the console for 30 seconds before restarting.
2. To rebuild the database:
   • Turn off your PS4 completely.
   • Press and hold the power button until you hear two beeps (about 7 seconds).
   • Connect your controller with a USB cable and select “Rebuild Database” from the Safe Mode menu.

5. Clear CMOS Memory (Advanced)

This step should only be attempted if you’re comfortable with hardware manipulation:

1. Unplug your PS4 and remove the cover.
2. Locate the CMOS battery on the motherboard.
3. Carefully remove the battery for about 5 minutes, then reinsert it.
4. Reassemble your PS4 and test the USB connection.

When to Contact PlayStation Support

If you’ve tried all these steps and still encounter the “USB storage device not connected” error, it’s time to seek professional help:

1. Visit the PlayStation Support website.
