If your PS4 is not reading an external hard drive, there could be a few different reasons why. Here are some troubleshooting steps to try:

- Check the External Hard Drive Compatibility: The first thing to check is whether your external hard drive is compatible with the PS4. The PS4 can only read external hard drives that are formatted in FAT32 or exFAT file systems. If your external hard drive is formatted in NTFS or any other file system, the PS4 won’t be able to read it. In this case, you will need to reformat the hard drive to FAT32 or exFAT. Be aware that reformatting the drive will erase all data on it, so be sure to back up your files before proceeding.
- Check the USB Port: The next thing to check is the USB port on your PS4. Try plugging the external hard drive into a different USB port on the PS4 to see if that solves the problem. If the drive works in another USB port, then the problem is with the original USB port, and you should have it serviced.
- Check the Cable: The USB cable that connects the external hard drive to the PS4 could be faulty. Try using a different USB cable to see if that resolves the issue. If the external hard drive works with a different USB cable, then the original cable is likely damaged and needs to be replaced.
- Check the Power Supply: External hard drives usually require their own power supply to operate. Make sure the power supply is plugged in and working correctly. If the external hard drive isn’t receiving enough power, it may not function correctly. If the power supply is faulty, you may need to replace it.
- Update PS4 Software: Sometimes, the PS4’s software can cause issues with external hard drives. Make sure your PS4 is running the latest software update. You can check for updates by going to Settings > System Software Update.
- Reset PS4: If none of the above steps have worked, you can try resetting your PS4. To do this, turn off your PS4 completely and unplug it from the power source. Wait for a few minutes and then plug it back in and turn it on again. This can sometimes solve issues with external hard drives not being recognized by the PS4.
- Use a Powered USB Hub: If your external hard drive requires more power than the PS4 can provide, try using a powered USB hub. This will supply additional power to the external hard drive, allowing it to function correctly. However, keep in mind that not all powered USB hubs will work with the PS4, so make sure to do your research before purchasing one.
In conclusion, if your PS4 is not reading your external hard drive, try the above troubleshooting steps to identify the issue and resolve it. If none of the above steps work, you may need to have your PS4 or external hard drive serviced.
