After determining the possible reasons for PS4 difficulties, it is critical to resolve the issue. Next, we'll put forward 8 ways to fix error CE 37857 0 on the PlayStation®4.

Fix 1. Check the PS4 USB connection

You should first verify the USB connection if you get the "PS4 USB storage device not connected" issue. You must confirm that the USB device is securely and correctly plugged into your PS4.

☞ Make sure the PS4 is correctly linked to the USB cable.

☞ Attempt to solve the issue by using a different USB port on the PS4.

☞ Verify whether USB 2.0 or 3.0 is supported by the USB device.

☞ It is advised that you attach any other USB device you have to the PS4 to see if the PS4 USB ports not working properly.

Fix 2. Turn off the PS4

Before turning your PS4 back on, disconnect it from the power source and wait a few minutes. This function helps the PS4 recover from any issues resulting from an unplanned power outage.

Step 1. First, take out the PS4's USB.

Step 2. Click Quick Menu and choose Turn Off PS4.


Step 3. Turn off the PlayStation 4 and let it for a few minutes.

Step 4. After that, turn it back on.

Step 5. Reconnect the USB and see if it will work correctly.

Fix 3. Clear CMOS Memory

Numerous issues with the PS4 architecture can arise from contaminated CMOS (Complementary Metal-oxide Semiconductor) memory. For that reason, before beginning any research, you should clear the PS4's CMOS memory chip. The tricky thing about this method is that it's not as simple as it seems, so to try this cure, you have to be tech-savvy or very intelligent.

Fix 4. Format the USB drive to FAT32 or exFAT

If the USB is not recognized by your PS4, there is an inconsistent file system format. The majority of USB formats are NTFS. But PS4 is limited to FAT32 and exFAT. In this part, two methods are provided to make the file system format inconsistent.

Option 1: Format the USB drive to FAT32/exFAT with Disk Management

Disk Management (DM), one of Windows' built-in disk formatting utilities, can help you format the USB drive to FAT32/exFAT with several clicks. However, the same as other native formatting tools (DiskPart or File Explorer), DM will cause permanent data loss as the cost. If you have backed up disk data first or you accept data loss, refer to the following contents.

Step 1. Click the Windows button, type disk management in the search bar, and select Create and format hard disk partitions.

Step 2. Right-click on the USB drive and choose Format.

Step 3. You can now configure settings such as Volume label, Allocation unit size, and File system. Choose FAT32 or exFAT. Check the Perform a quick format box and click OK.


Option 2: Convert the USB drive to FAT32 without data loss

As previously mentioned, formatting a storage device will delete the USB and cause complete data loss. Moreover, the FAT32 option might not be available as the default Windows formatting tool restricts FAT32 partitions to drives of 32GB or smaller.

What if your USB is larger than 32GB, and how to convert the USB drive to FAT32 without losing data? Don't worry. You can utilize AOMEI Partition Assistant Professional to get over them. With the help of this all-in-one partition manager, you can convert NTFS to FAT and vice versa without losing any data.

Additionally, it enables you to upgrade the 500GB PS4 to 1TB to increase storage capacity or enhance performance. Also possible is a data-loss-free PS4 hard drive clone to SSD.
