Remove the USB from your computer and plug in to the PS4 MD5 CHECK ANY PUP FILES BEFORE INSTALLATION! - HERE Make a folder on the root of your USB stick called, inside that a folder called, and put the for your chosen firmware in there (PUP's are found below). On PC: Format your stick to EXFAT using any suitable formatting tool. If this doesn't work a full factory format will be required to remove the pending update nag.

If you are on 5.05/6.72/7.02/7.55/9.00 and have a pending update try this: FTP in and delete the PS4UPDATE.PUP file in the /update folder, run update blocker, change your DNS to the ones at the top of this guide, reboot.To enter SAFE MODE, shut down your PS4, hold power to turn it back on and keep holding until you hear the second beep.

If you are on 1.00-8.52 and have a pending update, then update via SAFE MODE.If whilst on 5.05 or below you have ever run Update Blocker payload: you must use Update Unblocker first or FTP into your PS4 (port 1337) and delete the and the PS4UPDATE.PUP folders in the /update folder.If you have a PS4 above 5.50FW you should aim to update to the next closest firmware that supports jailbreaking: 6.72/7.02/7.55, or lastly 9.00. If you have a PS4 console running 5.01 or lower, follow the below section to upgrade to 5.05 via USB.Skip to page 96 of the manual (actually page 98 of the PDF) and have a read, if that helps. And hopefully you should have no problems after that. Then you can can format it with a file system however you like, or however you usually do. It will probably take quite some time, depending on the drive's capacity, but low level formatting will be complete. On most systems the internal disk will be first ( /dev/sda) and the one you want to format will be second ( /dev/sdb), and so on, but that's not always the case. Just make sure you specify the correct disk. That will basically overwrite the entire disk, including all partitions, etc with a fresh, blank slate. The command will look something like this: dd if=/dev/zero of=/dev/sdb Still nothing? Plug it into a Linux computer and zero the entire disk with dd. If you still have no luck, make sure you don't have any weird flags set. I guess sometimes there is some minor glitch when formatting that my device was particularly sensitive to. The same thing happened to my with my TV. If you have issues after formatting it again. Then I guess you have no choice but to use NTFS.

Unless you absolutely have to store individual files >4.0GiB on that disk.
