You can definitely format the SSD so that the PS5 can read it. In my case, however, the SSD was effectively "dead" and could no longer be read on the PC. I hope it's just a format read problem for you :)

Yes you can format the SSD, if it is not faulty, so that you can use it again.

Thank you very much, no....

I even sent it to the manufacturer and got it back the same way, saying it was flawless!
