SEAGATE Gamedrive for Playstation 4 (STGD2000200), hard drive
I connected this Ps4 storage device to my Ps4 and it worked, but when I restarted my Ps4, this device started piping, and I can no longer play my games that were on it, it shows me that I have no USB Device, although this hard drive is on USB, so better said it is not recognized, there's no point in restarting the Ps4 this game drive disk (STGD200020) is not recognized and I don't know what to do

You should reformat them. There's also an extra function.

ch

Yes, but we will format it without 'destroying' the data in it

Fa

Hmm, of course you can't. Check out the options in safe mode.

ch

K but thank you for your trouble: /

Fa

Yes sorry:/

It was the same for me, reformatting helped, but unfortunately the games were gone.

ch

Yes that's the thing, there are a lot of games on it that mean a lot to me and I don't want to lose the data that is on it
