Hello to all the community here,
I have now the same problem.
My ST3500620AS HP24 all of a sudden is not recognized anymore by BIOS.
If I install it as secondary drive, desktop takes a long time to boot up, and at the end it doesn't show up, nor windows recognize it anymore.
It's probably the bug which affects this particular drive and fw, and for which i red info on other threads
I don't have any tools unfortunately, nor i'm an electronic expert.
Can someone give me a hand to wake it up again?
