Part 2. Format PS4 USB Hard Drive to exFAT or FAT32

Usually, PS4 will not read usb properly due to the following error messages.

1. "The USB storage device is not connected"
2. "The USB storage device cannot be used. The files system is not supported"

Let's see another user story:

"Trying to connect an external flash drive to PS4, I keep getting an error saying that the storage device cannot be used. So annoying. How to get rid of the trouble? It's a 16GB Toshiba USB hard drive by the way."

In the first part, we arrived at a conclusion that PS4 won't read USB files due to invalid raw file system. And in the second part, the conclusion is different. In most cases, USB drives came with NTFS file system, which is not supported by PS4 game console. For your information, PS4 only recognizes exFAT and FAT32 file system.

So the solutions are the same. You have to convert raw to FAT32/exFAT or format NTFS to FAT32/exFAT. Check the detailed guide.

Step 1. Right-click My Computer(in Windows 7) or This PC (Windows 10), and select "Manage".

Step 2. Under Storage, click "Disk Management".

Step 3. Right-click on the USB partition and choose "Delete Volume...". Now, your USB hard drive is empty, showing as Unallocated.

Step 4. Right-click on the Unallocated disk and choose "New Simple Volume..."
