Fixing “The USB storage device is not connected” PS4 Error?

One of the most common, yet very annoying PS4 error messages is the one that says: “The USB storage device is not connected“. Sometimes this error message comes with a code number CE-37857-0 or SU-41333-4, and sometimes it doesn’t. This error message shows up due to several reasons, not necessarily a defective USB storage device as many may think. Additionally, there’re also various methods to fix this error and get PS4 to read the USB storage device again.

So, how to work around this issue? Is there any viable method you can rely on in this situation? Well, don’t panic, every error has its own fix. You have to be patient and try everything in order to find your way out.

Explaining The Error Message

the usb storage device is not connected - PS4 error message
The “The USB storage device is not connected” error message indicates that PS4 system is unable to recognize the USB storage device connected to it. In most cases, this error message only shows up with the USB storage devices used as an extended storage. For this reason, if you connect a flash memory stick to PS4, the system will easily recognize it.

Most often, this error suddenly occurs without any prior cue or hint. The USB storage device would work fine for a long time, then suddenly it stops working and this message appears. That’s it—It happens for no visible reason. That’s why it is so annoying and frustrating.

Sometimes this error occurs when PS4 or the external storage device falls down to the floor during the connection. This would cause an electrical shock that impacts the way PS4 system recognizes the USB-connected devices. If this is the case, it doesn’t imply necessarily a hardware defect. It may only mean that you need to fix system files that because corrupted.

Error Situations

There are three situations in which this error message appear.

  • When using the external storage device as an extended storage and trying to access it via the “USB Storage Devices” section. | Usually this error message comes with no error code.
  • It appears also when using the external storage device as a backup storage. When you go to the “Saved Data in System Storage” page and click the option “Copy to USB Storage Device” this error message shows up. It comes with error code (CE-37857-0). On its official twitter account, Sony suggests a quick fix for this error code:

    Connect the USB, go to [Sound/Devices] > [Stop Using Extended Storage] on the quick menu and then reconnect it. Make sure you reconnect it securely.
    Make sure the storage device is FAT or exFAT formatted.

  • When trying to update PS4 system software via a USB storage device. | This error message appears usually in the Safe Mode and has the error code (SU-41333-4). On its official twitter account, Sony suggests a quick fix for this error code:

    Format an USB to ExFAT.
    Download the system update to the USB and install it, from this link.
    Click on the “Download Update” blue button, go to “Update using a computer”.

These suggested fixes won’t always work, and the first situation needs additional efforts to fix.

So, let’s lay out the most common reasons for this case below.

Most Common Reasons

There are several reasons that sit behind this problem. When you get Error Message: “The USB storage device is not connected“, one of the following might cause it:

  • Defective USB Storage Device. | Usually the hard drive itself is fine, but the USB bridge that helps connecting the USB cable to the SATA interface of the hard drive is out of action.
  • Defective PS4 USB Port. | It happens sometimes due to the misuse of the PS4 USB port.
  • The USB cable that links the device to PS4 is damaged/cracked.
  • Connecting the USB storage device via a USB hub, or using a USB hub external hard drive. | PS4 doesn’t support storage devices connected via a third party medium (USB hub).
  • ِAbrupt power surge or electrical shock. | This may have ruined something between the PS4 and the hard drive that compelled PS4 system to stop recognizing it.
  • Improper installation of PS4 system software update. | If you have updated PS4, but due to some reason it didn’t go totally well, this might be one of the symptoms.
  • Improper installation of a game/app or its update. | The same thing we say here. But, additionally, bad installation of a game/app or its update can impact the functionality of the whole PS4 system.
  • Corrupted PS4 database. | Sometimes the reason is too trivial, and you only need to fix corrupted PS4 database.

There might be other reasons that we’ve missed, but according to our expertise, these are the most common.

Diagnosing the USB storage Device

Let’s first diagnose the USB storage device that the PS4 can’t recognize before moving on with the solutions. We want to know if the problem is with that device or with the PS4 system itself.

Doing that is pretty easy. All you need to know is either connect it to another PS4 or a PC/Mac system. If it works fine there and the system fully recognizes it, the source of problem is determined then, it’s the PS4 system.

Since most PS4 users don’t have more than one console, we’ll adopt the second option and connect the USB storage device to a PC.

Connecting PS4 USB Storage Device to a PC

So, once connected to a PC, you should get a message indicating that the system has properly recognized the connected USB drive. Otherwise, if the USB storage device is defective, you’ll get a message like the one below.

usb storage device not recognized on PC

Or you might not get any response at all from the system. This is a bad omen then. It indicates that the external hard drive is not functioning at all. It might mean that you have to buy a new one then.

Important Note

PS4 system fully encrypts USB storage devices used as extended storage. Therefore, after your PC recognizes the drive, you’ll find it listed in the “This PC” folder, but without any additional details. See the image below:

When you try to access it, this message appears:

Just click Cancel and don’t format the disk. Otherwise you’ll lose all your data stored on the external storage device.

Ok, but what if the drive is not listed on the “This PC” folder? Don’t worry, it happens often. Just go to Control Panel -> Administrative Tools -> Computer Management -> Storage Management. You should find it listed there as an unallocated storage.

If you see that, rest assured that the USB storage device is healthy and not defective.

Not Recognized By PC

Now, what if the system can’t recognize the connected USB storage device? Well, don’t panic, it’s not the end of our journey yet. Sometimes Windows System needs a restart to recognize newly-connected devices. So, what you can do is to turn off your PC, connect the external storage to it, turn it on now and let Windows do its job. If this still doesn’t work for you, most probably the storage device is defective. It might be the USB cable though that’s damaged. You have to do your own tests to figure out where the problem exactly is.

The reason might be the USB-SATA bridge which helps the external hard drive connect to USB cables. It might be defective.

USB-SATA bridge


If this is the case, you have to dismantle it and connect the hard drive internally to your PC, or externally via another external hard drive enclosure. Now, if you’ve established a new connection between the USB storage device and PC, check whether it works or not.

Fixing the Error

So, if you’ve already confirmed that USB storage device is working fine, we have to work on your PS4 then. In fact, in most cases the PS4 system is totally responsible for that error, not the USB storage device.

This error usually occurs because of a corrupted installation/update of PS4 system software. Sometimes, it happens right after updating or installing a game that’s not fully compatible with the current version of PS4 system software. This will cause conflicts within the PS4 system and impacts its functionality.

On the other hand, it might occur due to a defective PS4 USB port. Here, try to switch the port and see if this resolves anything. Try also to connect another USB storage device (e.g. Flash memory stick) to your PS4 and check whether it recognizes it or not via that specific port.

If that doesn’t work still, we’ll assume that the PS4 system needs maintenance and it what causes this issue.

If this really the case, you can easily fix it by either rebuilding PS4 database or initializing PS4.

Rebuilding PS4 database can resolve many issues related to PS4 performance. It won’t fix every single error, but it does fix a lot. In fact, you need to rebuild PS4 database regularly once every 6 months (or when needed) in order to maintain the best performance level of PS4.

As for initializing PS4, it is the last resort. You have to try the soft initialize first. If that doesn’t work, you go for the FULL initialize.

Important Notes

Before initializing PS4, you have to back up your game saves and screen shots either on the cloud storage or another USB storage device (if possible).

After the initialization is complete, the very first thing you have to do is to update PS4 system software to the latest version. That comes before anything else. After that, connect the USB storage device and check whether it works now or not.


PS4 Error Code (CE-37857-0)

The error message “The USB storage device is not connected” (or Error Code CE-37857-0, or SU-41333-4) is not that difficult to fix. You just need to be somewhat savvy and know exactly how to behave. If you have important data on the external hard drive that you’re not ready to lose, yet nothing of the above method worked, you better consult with an experienced technician. On the other hand, you’re totally welcome to discuss your issue with us via comments. Just leave us a comment and one of our experts will respond to you as soon as possible.

    I have tried all the options and it still doesn’t work. My wife spent over $100 for my bday to get me a seagate hard drive for PS4 . The PIN number is 2HJAP5-500. It’s not the PS4 or computer but it’s hard drive itself cause it recognized on my computer but not no one else’s . My PS4 can’t see the to recognize the hard drive . Still saids can’t find the hard drive .

    • PS4 Storage says:

      Have you FULL initialized PS4 (which includes re-installing the PS4 system software from scratch)? In most cases, the solution is that only. Please answer this question so we can help you more, if needed.

  2. Ed Cuddy says:

    I did a full initialization of my ps4 and its still not registering. I previously would plug it in and it wouldn’t read it but it would recognize it. What’s wrong? I tried to forget it and reconnect but I don’t know if that’s my mistake. It shows up on my PC but now with everything on it should I re-format it? I used it for applications only so I could easily re-download stuff.

    • PS4 Storage says:

      Full initialization might not work sometimes, so you’ll want to re-install PS4 system software. This will most probably fix the issue.

  3. Scott Vance says:

    I did all of the above it now recognizes the storage device but when I try to format it I get an error code CE-30016-0. Any advice would be appreciated. Thanks

  4. Ler says:

    I got this message and i don’t even use an external device at all

    • PS4 Storage says:

      Maybe someone else in your absence tried a faulty external hard drive then unsafely removed it and that caused this error.

      • Stacy says:

        We don’t have external hard drives in our house. My sons PS4 is displaying this error and we cannot figure out how to fix it.

  5. Tim says:

    I just recently got a TB 860 Evo and just got my PS4 Pro today. I’ve tried updating it with the latest firmware, formatting drives and making them exFAT, tried a 64 GB USB stick I just got this morning that came exFAT to start with, all with the update files and I can only choose option 6 but it never detects the USB. It worked with the stock Seagate HDD so I’m pretty sure it’s not the PS4. My computer detects all of the drives. I’ve pretty much tried everything tutorials say to do but nothing. And I know it’s not the SSD because the first thing I did was check it with Crystal Disk Info and all was good. Any ideas?

  6. Andre says:

    It say the USB storage Device is not connected. (SU-41333-4)

  7. Zachary T. says:

    i just purchased the 4 tb seagate game drive from my local gamestop guy said i can just plug it in and go from there but my system says no usb connected so i went through the whole blog and my game drive wasn’t formatted correctly i am now waiting on it to finish formatting (i have no clue when because there is no progress bar) but im worried that something might be wrong with the playstation system. any help or reassureance?

    • PS4 Storage says:

      If you’re sure that your external HDD is healthy (test it by connecting it to a PC), that means the PS4 itself has problems.

      Try to change the USB port. The PS4 must recognize every USB storage device connected to it, and a message will show up telling you to format it. This is the normal situation. But since this didn’t happen, you have to initialize the PS4 system (FULL). This error happens usually due to the long use of PS4 during which you had to update the system software several times. This accumulates lately and generate errors in the system functionality. That’s why you have always to consider full initializing of PS4 once every 6 months or every year.

  8. brandi gaye says:

    Did everything mentioned and nothing changed. My seagate tb randomly stopped working today in the middle of game play. This seems to be a Playstation issue, so what should be my next steps? Do I need to send my playstation some where or what?

    Yes, I rebuilt, initialized and tested everything such as different usb things and they all connected, but NOT my external hard drive. Yes, i connected the hard drive to a computer and it said it was working just fine.

    • PS4 Storage says:

      Probably there’s a compatibility issue with your external hard drive firmware and the installed PS4 system software. All you can do is either to use another external HDD, or wait for a new update for the PS4 system software.

  9. Jason says:

    I made sure the HDD is healthy..and formatted to correct format. I tried the Sound and Device way..and it wasn’t listed there…initialized the ps4 and that didn’t do anything either…really irritating. Any idea would be great

    • PS4 Storage says:

      Switch the USB port. If that doesn’t work, you need to FULL initialize the PS4 and reinstall the system software from scratch. If this doesn’t work still, it is either a compatibility issue between your storage device firmware and the PS4 system, or it’s a hardware issue—Either the PS4 USB ports are malfunctioning or the USB cable of the hard drive needs replacement. After all, tests will manifest the real source of problem.

  10. Hdjd says:

    I have tried everything, completely restarting my PS4, initializing it, wiping everything, updating it, and nothing is working. It was working fine yesterday, then my sister downloaded Sonic Forces, and now nothing works.

    • PS4 Storage says:

      What exactly is happening with you? Does the external hard drive light come on? Have you tried connecting the external HDD to a PC to check whether it functions there or not? Please provide us with further details so as to be able to properly help you.

  11. Rahim Lofland says:

    Had anyone rieceved any help? Mines was working fine s few months ago now I’m getting the not connected message.. it’s a Sony/segate external hard drive and I’m not getting help from don’t or Seagate and before you ask yes I have tried all the options above

  12. Omar Osman says:

    First off, i’d like to say what an awesome site this is. I need your help guys. My playstation prompts me to install new update software on it when i open it. I downloaded the update on the correctly formatted USB yet the playstation fails to read it giving me “The USB storage device is not connected SU-41333-4” message. I tried all the Safe mode options, none of them work. I removed the internal HD and connected it to my MAC then formatted that as well but still the same problem. Any idea what i could do?

    • PS4 Storage says:

      Hi Omar and welcome to our website,

      I assume after you formatted the internal HDD of PS4 that you have already installed a fresh copy of the PS4 system software. This requires a working USB storage device for this operation to complete. How could you do that while you already got that error?

  13. Gabe O'Brien says:

    Hey guys, So I dropped my ps4 and when starting up my ps4 I got the SU-41333-4 error code. I tried all of the safe mode options 1-6 as well as downloading the 7.51 software to my hard drive. The hard drive showed all the signs of functioning with the light and there were no errors with naming the files and whatnot. So when I go to initialize with the safe mode option 7 it recognized my hard drive but after loading for a bit it says “Cannot Initialize (CE-33567-4). I can’t find anything online about that error code and I have no idea what to do next.

    • PS4 Storage says:

      CE 33567-4 indicates the external USB can’t be recognised then initialised for PS4 use, commonly it is caused by incompatible partition format. You may fix this if you have Windows computer. Just plug the drive to a computer running Windows 7 or higher, then

      • Step 1: Click “Start”, and then select “Run” option.
      • Step 2: Input “diskpart” at the prompt.
      • Step 3: Input “List disk”, and then press “Enter”
      • Step 4: Select the disk needs to be converted by inputting “select disk …”
      • Step 5: Input “Clean” command, and then the disk selected will become an unallocated space, and all data will be deleted.

      After using Diskpart Command, only unallocated space is on your disk (so no NTFS or FAT32 or xFAT), now just disconnect the hdd from your pc and put it in the ps4 and re-initialize.

  14. Yes says:

    Just bought a sea gate game drive 2 tb and I connected to my ps4 hoping it would work b ur I didn’t receive no pop up and when u go to check it just tells me there’s no usb storage device connected

    • PS4 Storage says:

      Try to connect the drive to a PC and see whether it recognizes it or not. If it does, the problem then is with your PS4, you most probably need to full initialize it.

  15. rob says:

    I’ve done everything,and I’m stuck in a safe mode option 7 drive,and system saying cant use USB device..dont know what to do now.

    • PS4 Storage says:

      Connect the USB device to a PC and check whether it works or not. If it does, go format it and try again. If not, try another USB storage device.

  16. Russell says:

    I bought a seagate backup plus slim 1TB 3.0 hard drive from online.When I plug it in,it says the usb device is not connected,it still shows a blue light.I tried the other USB port but still no succes.I even went to test it on the pc and it says it’s fine healthy condition.The funny thing is that my old seagate 2.0 version can be seen when I plug it in except my 3.0 usb that I just bought

    • PS4 Storage says:

      You have to initialize the PS4 and reinstall the operating system. The external HDD driver might be corrupted and thereby the PS4 system can’t install it.

  17. Brandon Hoffman says:

    So my external hard drive has always worked but just got unplugged on accident and now the PS4 isn’t reading it anymore and I’ve done virtually everything but initialize the PS4. So if anyone is still on this and can help that would be great.

    • PS4 Storage says:

      There was probably an electric shock occurred when that accident happened. This shock can affect the functionality of the operating system or even the USB port itself.

      The first thing you have to do in this situation is to check whether the external hard drive is still healthy or not by connecting it to a PC and checking whether it works fine or not.

      If the external HDD is still working, you have to consider full initializing the PS4 and reinstalling the PS4 system software.

  18. Jordan says:

    My situation is frustrating because it is neither the HDD or the PS4.. I already have a 1TB External HDD which works fine but is nearly out of space so upgraded to 2TB. The PS4 is not recognising the new HDD BUT still recognises the old one when I plug that in and before you ask.. YES I only plug one in at a time and YES I have checked the 2TB HDD on my laptop and it recognised fine. It was FAT32 format and I even tried formatting to ExFAT hoping that would resolve the issue and it didn’t.

    The 2TB HDD lights up and flashes blue when plugged int0 the PS4 but the PS4 does not prompt to format it nor does it recognise it when you g to storage or USB devices. Highly retarded..

    • PS4 Storage says:

      It seems like it’s a problem with the PS4 system itself. You can confirm that by trying the external HDD on another PS4 and check whether it works or not. If it does, you have to full initialize the PS4 and reinstall the operating system.

  19. pratham patel says:

    see i chose to click the option stop using this as an extended storage while in the background i was having spotify error so i clicked the option but now it shows no usb device connected

    • PS4 Storage says:

      Most probably the PS4 system got corrupted. You have to initialize the PS4 in order to work around this issue.

  20. Nachiket Bidkar says:

    I was downloading some games from the PS Store last night and my Seagate External hard drive was installing the games properly at a quick pace but when I checked an hour later the PS4 displayed a message that it no longer recognised the hard drive. I connected the hard drive to a PC and it recognises it although it doesn’t directly show it in mypc. I also swapped the cables of the hard drive and connected it to different USB ports. I then tried connecting usb flash sticks and the PS4 recognised them without any issues. I’ve also rebuilt the database. So should I just try formatting the hard drive on PC and use it again as extended storage? The hard drive is barely 2 months old and I haven’t backed up any saved data so I’m not losing much but I can’t afford to let it die so soon. If you agree that I should format it, how do I do it since it doesn’t show up in mycomputer folder.

    • PS4 Storage says:

      This is a very common issue with the PS4 system. There has been a system file conflict with the external hard drive driver files that hindered the PS4 system from recognizing it again.

      I’m afraid to say that you don’t need to format the external HDD, rather you need to full initialize the PS4.

      You may try though to format the PS4 external HDD. Please visit this page and follow the instructions on how to format it.
