First off, let’s clear something up: you’re not alone. This error is super common, and the good news is, it’s usually fixable. Most people think the problem is with their USB device, but that’s not always true. Your PS4 can be pretty picky sometimes and might just be having a bad day.

So, what can we do about this pesky error [SU-41333-4]? Is there a magic trick to make it go away? Don’t panic! There’s always a solution to these tech hiccups. The key is to stay calm and try different things until something works.

Explaining PS4 Error [SU-41333-4] Message

Ever seen this message on your PS4: “The USB storage device is not connected [SU-41333-4]”? It’s like your PS4 is saying, “Hey, I can’t see the USB thing you plugged in.” This mostly happens with USB devices used for extra storage. Strangely enough, if you use a USB flash drive, the PS4 usually has no problem recognizing it. But sometimes, it gets more confusing and this error shows up no matter what USB device you use.

Imagine this: you’re using your USB device with your PS4, everything’s fine, and then out of nowhere, it stops working. This error message pops up without any warning. It’s like your PS4 just decided to be grumpy for no reason at all. That’s why it’s so annoying!

Why Would PS4 Error [SU-41333-4] Occur?

There are a few reasons why your PS4 might start acting up like this. Sometimes, if your external hard drive gets a bit of a rough treatment, like if it falls down (especially when it’s plugged into your PS4), it can mess things up. This might cause an electrical short – basically, a tiny zap – that affects how your PS4 talks to USB devices. Or, it might send a surge of power to your USB device. But don’t worry, this doesn’t always mean your hardware is broken. Sometimes it just means some files got mixed up and need fixing.

Another reason could be that the cable of your external hard drive is damaged, or maybe the USB port on your PS4 where you plug it in isn’t working right.

Methods to Fix Error [SU-41333-4]

Got the “The USB storage device is not connected [SU-41333-4]” error on your PS4? Don’t worry! There are a few common situations where this error pops up, and I’ve got some handy tips to help you fix it.

Where You Might See This Error:

  • Using External Storage: This error often shows up when you’re trying to use your external storage through the “USB Storage Devices” section. It usually doesn’t have an error code with it.
  • Using Backup Storage: If you’re backing up your saved data to a USB, this error might appear, especially when you select “Copy to USB Storage Device.” Sony’s official Twitter account suggests:
    • Reconnect your USB by going to [Sound/Devices] > [Stop Using Extended Storage] on the quick menu, then plug it back in carefully.
    • Make sure your storage device is formatted as FAT or exFAT.
  • Updating PS4 System Software via USB: This error can also pop up in Safe Mode when you’re updating your system. Sony suggests:
    • Format a USB to ExFAT.
    • Download the system update to the USB and install it. You can find the update here.

These fixes might not always work, especially in the first case, where you might need to try a few different things.

Most Common Reasons

  • Defective USB Storage Device: Sometimes, it’s not the hard drive itself but the USB bridge that connects the USB cable to the hard drive.
  • Defective PS4 USB Port: Misusing the USB port can lead to this issue.
  • Insufficient Power to PS4: If your PS4 isn’t getting enough power, it might struggle to run power-hungry external hard drives.
  • Damaged USB Cable: A cracked or damaged USB cable can be the culprit.
  • Using a USB Hub: PS4 doesn’t like storage devices connected through a USB hub.
  • Power Surges or Electrical Shorts: A sudden power issue could disrupt the connection between your PS4 and the hard drive.
  • Faulty System Software Installation: If a system update didn’t install correctly, it could cause this error.
  • Bad Game/App Installation: Sometimes, a poorly installed game or app (or its update) can mess with your entire PS4 system.
  • Corrupted PS4 Database: Often, the issue is just a corrupted database, which is fixable.

There could be other reasons, but these are the most common ones based on our experience.

Basic troubleshooting

If you’re facing that pesky “The USB storage device is not connected [SU-41333-4]” error on your PS4, let’s start with some basic steps to try and fix it. These are simple things you can do at home without needing any special tools or skills.

Step 1: Turn Off Your PS4 Completely

The first thing you want to try is basically giving your PS4 a little break. Here’s what you do:

  • Turn off your PS4 completely. Not just sleep mode, but totally off.
  • Unplug it from the power source.
  • Wait for about 3-5 minutes. This short wait can help your PS4 shake off any minor glitches, especially those caused by sudden power issues.

And Don’t Forget Your USB Device!

While your PS4 is taking its mini-break, unplug your USB storage device too. Then, before you turn your PS4 back on, plug the USB device back in while the PS4 is still off. After that, power on your PS4 and see if it recognizes the USB device now.

Step 2: Try a Different USB Storage Device

Got another USB storage device lying around? Great! Give it a try on your PS4. This step is super helpful because it tells you if the problem is with your PS4’s USB port or the original USB device you were using. If the new USB device works without any issues, then we might have found our culprit!

Clear the CMOS Memory

Dealing with that stubborn “The USB storage device is not connected [SU-41333-4]” error on your PS4? Another step you can try is clearing the CMOS memory. This might sound a bit technical, but it’s a useful trick for fixing various PS4 errors.

CMOS stands for Complementary Metal-Oxide-Semiconductor. It’s a little chip in your PS4 that stores information like system settings and the date and time. Sometimes, the data in the CMOS can get mixed up or corrupted, leading to errors like the one you’re facing.

Clearing the CMOS memory is not as straightforward as the previous steps and requires a bit more technical know-how. It’s not just a couple of button presses; you might need to open up your PS4. So, this step is best for those who are comfortable with tech and hardware.

If you’ve tried clearing the CMOS memory and you’re still seeing that error message, don’t worry. There are more methods to try. It’s all about finding the right solution for your specific situation.

Diagnosing the USB storage Device

If you’re still seeing the “The USB storage device is not connected [SU-41333-4]” error on your PS4, it’s time to check if the problem is with your USB storage device or the PS4 itself. Don’t worry, this is easier than it sounds!

Test the USB Device on Another System

The simplest way to test your USB storage device is by connecting it to a different device, like another PS4 or a PC/Mac. If it works fine there and gets recognized without any issues, then we know the problem is likely with your PS4, not the USB device.

Most People Don’t Have Two PS4s, So…

Let’s go with the more common option: connecting your USB storage device to a PC. Here’s what to look for:

  • When Connected to a PC:
    • If the PC recognizes the USB drive, you’ll get a notification about it.
    • If the USB device is defective, you might see an error message, or the PC might not respond to it at all. If that happens, it could mean your external hard drive isn’t working and might need replacing.

Important Note About PS4 and USB Devices

PS4 encrypts USB devices used for extended storage, so when you plug it into a PC:

  • The drive will show up in the “This PC” folder, but it might not show any details.
  • If you try to access it, a message might pop up asking to format the disk. Do not format it, or you’ll lose all your data on the external storage device.

What If the Drive Isn’t Showing Up?

No panic! If the drive doesn’t show up in the “This PC” folder, here’s what you do:

  • Go to Control Panel -> Administrative Tools -> Computer Management -> Storage Management.
  • Look for your drive there. It might be listed as unallocated storage.

If you find it there, good news! It means your USB storage device is probably fine, and the issue might be with the PS4.

Not Recognized By PC

Facing that “The USB storage device is not connected [SU-41333-4]” error on your PS4, and now your PC won’t recognize the USB storage device either? Let’s not lose hope just yet! There are still some steps you can take to figure out what’s going on.

Try Restarting Your PC

Sometimes, your computer just needs a little nudge to notice new devices. Here’s what you can do:

  • Turn off your PC.
  • Connect the external storage device to it.
  • Turn on your PC and give Windows a chance to detect the device.

Still No Luck?

If your PC still doesn’t recognize the USB device after a restart, it’s possible the device itself might be having issues. It could be the USB cable that’s damaged, or there might be another problem. You’ll need to do a bit more digging to find out exactly where the issue lies.

Investigating the USB-SATA Bridge

A common culprit could be the USB-SATA bridge. This is a part of your external hard drive that helps it connect to USB cables. If this bridge is having problems, your device might not work correctly.

What to Do Next?

If you suspect the USB-SATA bridge is the issue, here’s a way to check:

  • Dismantle the External Hard Drive: Carefully open up the external drive.
  • Connect the Hard Drive Directly: Try connecting the hard drive directly to your PC. You can do this by:
    • Installing it internally in your PC, or
    • Using another external hard drive enclosure.

Testing the New Connection

Once you’ve set up this new connection between your USB storage device and the PC, see if it’s recognized now. If it works, you’ve found the issue! If not, the problem might be deeper within the hard drive itself.

Fixing the [SU-41333-4] Error

If you’re still seeing the “The USB storage device is not connected [SU-41333-4]” error on your PS4 and you’ve confirmed that the USB storage device is fine, then it’s time to focus on your PS4. In many cases, it’s actually the PS4 system that’s responsible for this error.

Possible Causes Within the PS4

  • Corrupted PS4 System Software: This error often happens due to a corrupted installation or update of the PS4 system software.
  • Incompatibility Issues: Sometimes, installing or updating a game that’s not fully compatible with your current PS4 system software can cause conflicts.
  • Defective PS4 USB Port: Try using a different USB port on your PS4 or try a different USB device, like a flash memory stick, to see if the port is the issue.

Steps to Fix the Issue on PS4

  • Rebuilding the PS4 Database: This is a great first step as it can resolve many PS4 performance issues. It’s recommended to do this every 6 months or as needed.
  • Initializing PS4: This is more of a last resort. Start with a soft initialization, and if that doesn’t work, try a full initialization.

Important Notes Before Initializing

  • Back Up Your Data: Before initializing your PS4, make sure to back up your game saves and screenshots to cloud storage or another USB storage device.
  • Update After Initialization: Once the initialization is complete, the first thing you should do is update your PS4 system software to the latest version. Then, try connecting your USB storage device again.

A Tip from a Fellow PS4 User

One of our readers, Ryan Welz, shared a tip that worked for him:

  • Exiting Safe Mode: Hold down the start button for 10 seconds when powering up the system. Plug the USB into the center port, and you should see a screen with options. Select option 6 to initialize your PS4. This might help you get out of safe mode and resolve the SU-41333-4 error.


Dealing with the “The USB storage device is not connected” error (also known as Error Code CE-37857-0 or SU-41333-4) on your PS4 can be a bit of a challenge, but it’s definitely manageable. You don’t have to be a tech wizard; just a bit of know-how and the right steps can lead you to a solution.
