  2. Turn Off PS4: Select Turn off PS4.

Moving Games From An HDD To An External SSD/HDD

According to my experience, the PS4’s HDD could be corrupt or malfunctioning in some other way, contributing to the PS4 error SU-30638-0. Transferring the games to an external HDD or SSD connected to your PS4 will free up space and ensure they function as intended.

Ensure your external HDD or SSD has a USB 3.0 connection and roughly 250 Gigabytes of space. When you attach a compatible external hard drive, the PS4 will prompt you to format it.

You can accomplish this by following the steps below:

  1. Device Menu: Open the device menu from the main settings.
  2. USB Storage Devices: Select USB storage devices to find your recently plugged-in device.
