If you’re a PlayStation 4 owner, you know that there’s no way to use your internal hard drive as your primary storage. That’s because PlayStation 4 uses an external hard drive as its primary storage. To use an external hard drive on your PlayStation 4, you first need to create a new account on the PlayStation Network and then sign in. Once you’re signed in, go to the Storage section and click on the link to create a new storage account. Once you’ve created a new storage account, go to the My Games & Apps section and click on the link to add an external hard drive as your primary storage device. You’ll need to provide a name for your new hard drive and select the type of hard drive ( SATA or USB). You can also choose whether or not to include any games or applications on your new hard drive. Once you’ve added your external hard drive as your primary storage device, go back to My Games & Apps and select it from the list of devices. You’ll now be able to play any games or applications that are installed on your internal hard drive without having to worry about space issues.
