Not sure if this will get an answer, but I'll try.
I have a Seagate external hard drive for my PS4 - I've been using it for a couple years withotu issues. But recently I can't use it anymore, I get a message saying ce-41902-6 error. Is there any way to fix that? Do I have to format it? And if so can I do it from the PS4?
Edit: for context, the USB port is working properly as I can insert a USB drive into without issues, and I have the latest system update installed.
